Keeping this in consideration, is it possible to orient a current loop in a uniform magnetic field so that the loop does not tend to rotate explain use equations to show your reasoning?
Yes. If the magnetic field is directed perpendicular to the plane of the loop, the forces on opposite sides of the loop will be equal in magnitude and opposite in direction, but will produce no net torque on the loop.
Subsequently, question is, how should you orient a current carrying wire in a uniform magnetic field? how should you orient a current-carrying wire in a uniform magnetic field for the wire to experience a maximum force? why? the wire should be perpendicular to the magnetic field for maximum force since F=ILBsintheta and if I, L, B are constant then sin90=1 will give you the greatest force.
Also question is, is the magnetic field due to a current loop uniform?
A uniform magnetic field exerts no net force on a current loop but it does exert a net torque. The two forces are in opposite directions so there's no net force but there is a torque that tends to make the loop rotate about an axis running through the center of the loop.
How can a current loop be used to determine the presence?
The loop can be mounted on an axle that can rotate. The current loop will rotate when placed in an external magnetic field for somearbitrary orientation of the field relative to the loop. As the current in the loop is increased, the torque on it will increase.
Is it possible for a current loop to stay without rotating in a uniform magnetic field?
Yes, it possible to orient a current loop in a uniform magnetic field such that the loop will not tend to rotate.What is the net force acting on a compass needle in a uniform magnetic field?
So, apart from torque, the magnetized needle experiences a force. A magnetised needle in a uniform magnetic field experiences a torque but no net force because the forces experienced by it are equal in magnitude, opposite in direction and have different lines of action. Therefore, the net force is zero.How do you stop a magnetic field?
If you want to block out magnetic "force," your best bet is to re-route magnetic field lines (lines of magnetic flux) around the object that is sensitive to those lines. Do this by shielding the object in a material with a much higher magnetic permeability of the surrounding materials.What is the formula for magnetic field?
Magnetic Field Formula. The magnetic field formula contains the constant^{mu_{0}}. This is known as permeability of free space and has a value^{mu}_{0} = 4pi imes 10^{-7} (T cdot m/ A). Besides, the unit of a magnetic field is Tesla (T).What is the current in the loop?
The Loop Current is a flow of warm water that travels through the Gulf of Mexico, past the Florida Keys, and up the Atlantic Seaboard. The Loop Current is an area of warm water that travels up from the Caribbean, past the Yucatan Peninsula, and into the Gulf of Mexico.How do you find the magnetic field of a loop?
The magnetic field strength at the center of a circular loop is given by B=μ0I2R(at center of loop), where R is the radius of the loop. RHR-2 gives the direction of the field about the loop.Why do two wires attract?
When the currents flow in the same direction the magnetic field will be opposite and the wires will attract. If the currents flow in opposite directions, the electrons will "see" a higher density of electrons in the other wire due to relativistic length contraction. And the wires will repel.What is the magnetic field between two parallel wires?
Note that two wires carrying current in the same direction attract each other, and they repel if the currents are opposite in direction. the magnetic field at wire 2 is B = Tesla = Gauss. If current I2 = Amperes. then the force per meter is F/ΔL = Newtons/m. The earth's magnetic field is about 0.5 gauss.What is the magnetic field inside a solenoid?
A solenoid is a long coil of wire wrapped in many turns. When a current passes through it, it creates a nearly uniform magnetic field inside. The energy density of the magnetic field depends on the strength of the field, squared, and also upon the magnetic permeability of the material it fills.What is the magnetic field at the center of the loop?
The magnetic field strength at the center of a circular loop is given by B = μ 0 I 2 R (at center of loop) , B = μ 0 I 2 R (at center of loop) , where R is the radius of the loop. RHR-2 gives the direction of the field about the loop.What happens when a current carrying conductor is placed in a magnetic field?
When a conductor carrying a current is placed in a magnetic field, the conductor experiences a magnetic force. The direction of this force is always right angles to the plane containing both the conductor and the magnetic field, and is predicted by Fleming's Left-Hand Rule.What is the relationship between force and current?
Current is directly proportional to magnetic force for a straight current carrying conductor in a uniform magnetic field. So the force is directly proportional to the size of the current. Practically this means the following: If the current is doubled the force on the conductor will double.What happens to a current carrying conductor in a magnetic field?
If the current-carrying wire is placed in a magnetic field (whose lines of force are at right angles to the wire) then it will experience a force at right angles to both the current direction and the magnetic field lines. The force increases if the strength of the magnetic field and/or current increases.What is the direction of the magnetic force?
It states that, to determine the direction of the magnetic force on a positive moving charge, you point the thumb of the right hand in the direction of v , the fingers in the direction of B , and a perpendicular to the palm points in the direction of F .What is current force?
current force. The force that exists today. The current force represents actual force structure and/or manning available to meet present contingencies. It is the basis for operations and contingency plans and orders. See also force; Intermediate Force Planning Level; Programmed Forces.Is force perpendicular to current?
Magnetic Force on a Current-Carrying Wire. The magnetic force on a current-carrying wire is perpendicular to both the wire and the magnetic field with direction given by the right hand rule.How do you find the force of a conductor?
Calculate the force acting on the wire when it is placed at right angles in a 0.60 T magnetic field.- 5.0 cm = 5 ÷ 100 = 0.050 m.
- force on a conductor carrying a current = magnetic flux density × current × length.
- force = 0.60 × 0.75 × 0.050.
- force = 0.0225 N.
