# Magnetic force on a loop

**Electricity and Magnetism**Level pending

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 ]
