A coil is free to rotate in a magnetic field with a flux density of 33 mT. The coil has 50 loops and an area of 25 cm2. A current of 0.75 amps flows through the coil. When the plane of the coil makes a certain angle with the magnetic field, the torque on the coil is 2.8 × 10–3 N m. If the coil rotates until this angle is doubled, what is the percentage change in torque?
