Part A An 1200-turn coil of wire that is 2.3 cm in diameter is in a magnetic field that drops from 0.15 T to 0 T in 12 ms. The axis of the coil is parallel to the field. What is the emf of the coil? Express your answer in volts. For the steps and strategies involved in solving a similar problem, you may view a Video Tutor Solution. E = V

I am working on some physics homework and am stuck on this one.  Any help would be great, thanks!

The solenoid shown in the diagram has 5 loops per centimeter and a cross sectional area of 0.3 m². The resistor has the resistance of 2 Ohm. When the switch is closed, the current in the solenoid increases at the rate of 200 A/s. Find the current through the resistor. R

A coil has 180 turns enclosing an area of 10.4 cm². In a physics laboratory experiment, the coil is rotated during the time interval 0.046 s from a position in which the plane of each turn is perpendicular to Earth's magnetic field to one in which the plane of each turn is parallel to the field. The magnitude of Earth's magnetic field at the lab location is 5.00×10-5 T. Part A What is the magnitude of the magnetic flux through one turn of the coil before it is rotated?
