Question

An 8.00 x 10^6 kg electromagnet built in Switzerland draws a current of 3.00 x 10^2 A. How much charge passes through the magnet in 2.4 min?

Answer 1

In 2.4min (= 144 sec) with a current of 3x10² A the charge of the value
Q = It = 3x10² [A]*144[sec] = 4.32x10⁴ C passes through the magnet.
