Question

The torque experienced by current carrying loop of magnetic moment m(vector) placed in a magnetic field (vector B) is

Answer 1

hhTorque

Torque(τ) is the twisting force that tends to cause rotation. The axis of rotation is the point where the object rotates.

τ = F×r

Where F – force applied and r – the distance between the centre of the axis of rotation and to the point where force is applied.

Torque On Current Loop, Magnetic Dipole

A magnetic dipole is the limit of either a closed loop of electric current or a pair of poles as the dimensions of the source are reduced to zero while keeping the magnetic moment constant. Now we shall show that a steady current I passing through a rectangular loop placed in a uniform magnetic field experiences a torque. It does not experience a net force. This behaviour is similar to the of an electric dipole in a uniform electric field.mark as brainlist

Answer 2

Heyaa,

● Answer-
τ = m×B

● Torque-
- Torque is a measure of how much a force acting on an object causes that object to rotate.
- It's given by formula -
τ = r×F

● Torque in magnetic field -
- Torque experienced by current carrying loop in magnetic field is given by-
τ = m×B
Where all three are vector quantities.

Hope it helps...
