I need help with physics questions
1- Imagine a B-field is at 45o to the plane of a coil of wire loops. The coil of wire has 540 loops with a radius of 5 cm. If the magnetic field, B, is reduced from 4 T to 2 T in 3 seconds, what is the average induced EMF in the coil?
2- Electrons in an x-ray machine are accelerated through 120 kV and directed toward a target to produce x-rays. Calculate the power of the electron beam in this machine if it has a current of 13.0 mA.
3- An oxygen 16 ion with a mass of 2.69×10^−26 kg travels at 4.9×10^6 m/s perpendicular to a 1.23 T magnetic field, which makes it move in a circular arc with a 0.234 m radius. What positive charge is on the ion?

Imagine that we have a coil consisting of N turns of wire shaped like a circular loop with radius R. We place this coil in a uniform external magnetic field that points perpendicular to the face of the coil. Imagine that the magnitude of this external field is given by the formula B(t) = B_o cos(omega t - phi) where B_o, omega and phi are all constants. Find an expression for the induced emf in the loop as a function...
