Force on a Loop in a Changing Magnetic Field

Question

A circular wire loop with radius r and mass m is placed in a uniform magnetic field oriented perpendicular to the loop's plane. The magnetic field's magnitude varies with time t according to the function B(t) = B₀e^(αt). If the loop is initially at rest, what is the magnitude of its acceleration at t = 0?

Accepted Answer

0

Answer

$$\dfrac{2\pi^{2}r^{3}B_{0}\alpha}{m}$$

Answer

$$\dfrac{\pi r^{2} B_0 \alpha}{m}$$

Answer

$$\dfrac{\pi r^{2} B_0^{2} \alpha}{m}$$
