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?
What is the magnitude of the magnetic flux (Pinitial) through the coil before it is rotated? Express your answer numerically, in webers, to at least three significant figures. Constants View Available Hint(s) In a physics laboratory experiment, a coil with 220 turns enclosing an area of 12.2 cm2 is rotated during the time interval 3.70x10-2s from a position in which its plane is perpendicular to Earth's magnetic field to one in which its plane is parallel to the field. The...
