Problem
Two separate circular loops, A and B, are made from the same conducting wire.
• Loop A has a radius of 8 cm and carries a current of 3 A.
• Loop B has a radius of 6 cm and carries an unknown current IB.
Assuming each loop consists of a single turn, determine the value of IB required so that the magnetic field at the centre of loop B equals that at the centre of loop A.
