Question

A magnetic field is produced and directed along y-axis. A magnet is placed along y-axis. The direction of torque on the magnet is (A) in the x-y plane (B) along y-axis (C) along z-axis (D) Torque will be zero

τ= vec M × vec B hat i × hat j = hat k The direction of torque will be always Z- axis (+ ve )

Q. A magnetic field is produced and directed along y-axis. A magnet is placed along y-axis. The direction of torque on the magnet is

in the x-y plane

along y-axis

along z-axis

Torque will be zero

$τ = M \times B$
$\hat{i} \times \hat{j} = \hat{k}$
The direction of torque will be always $Z -$ axis $(+$ ve $)$

along z-axis

Torque will be zero

τ=M×B i^×j^​=k^ The direction of torque will be always Z− axis (+ ve )

$τ = M \times B$
$\hat{i} \times \hat{j} = \hat{k}$
The direction of torque will be always $Z -$ axis $(+$ ve $)$
