Question

A current-carrying loop is placed in a uniform magnetic field. The torque acting on it depends upon

• A. area of loop
• B. value of current
• C. magnetic field
• D. all of these

Answer 1

Answer: (D)

all of these

The torque acting on a current carrying loop placed in a uniform magnetic field is,

$\tau =IABsin\theta$

where, $I=$current flow in loop

$A=$Direction of the area vector

$B=$ uniform magnetic field

The torque acting on a current-carrying loop placed in a uniform magnetic field depends upon

1) area of the loop

2) value of current

3) magnetic field

So option D is correct
