Two coils are wound around the same cylindrical form. When the current in the first coil is decreasing at a rate of -0.245 A/s , the induced emf in the second coil has a magnitude of 1.70×10?3 V .

Part A

What is the mutual inductance of the pair of coils?

Part B

If the second coil has 29 turns, what is the flux through each turn when the current in the first coil equals 1.15 A ?

Part C

If the current in the second coil increases at a rate of 0.365 A/s , what is the magnitude of the induced emf in the first coil?

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc
