# Magnetic force on a loop

A long wire carrying current $$I$$ is fixed near a fixed conducting square coil of resistance $$R$$ as shown in the figure. The current in the long wire varies as $$I = I_0t$$. Find the net force acting on the coil at t = 2sec. Find the answer in SI units. [given $$I_0 = \frac{4\pi}{\mu_0} A/s, a = 1m, R = 2\Omega$$ and ln2 = 0.693 ]
