Question

Assertion $\left(A\right)$ : When a magnet is placed in a non-uniform magnetic field , it experiences both translatory and rotatory motion.

Reason $\left(R\right)$ : The poles of the bar magnet experiences resultant force and torque.

• A. Both $\left(A\right)$ and $\left(R\right)$ are true, $\left(R\right)$ is the correct explanation of $\left(A\right)$
• B. Both $\left(A\right)$ and $\left(R\right)$ are true, $\left(R\right)$ is not the correct explanation of $\left(A\right)$
• C. $\left(A\right)$ is true but $\left(R\right)$ is false.
• D. $\left(A\right)$ is false but $\left(R\right)$ is true.

Answer 1

The correct option is A Both $\left(A\right)$ and $\left(R\right)$ are true, $\left(R\right)$ is the correct explanation of $\left(A\right)$


When a magnet is placed in a non-uniform magnetic field, it experiences non-zero net force and net torque.

Due to non-zero net force, it will have translatory motion. Due to non-zero net torque, it will have rotatory motion.
