(a) Define self and mutual induction. Give practical examples of both inductions.
(b) A circular coil of wire with 450 turns and a radius of 8.5 cm is placed horizontally
on a table. A uniform magnetic field pointing directly up is slowly turned on, such
that the strength of the magnetic field can be expressed as a function of time as:
B(t) = 0.03 (T /s?) x t. What is the total EMF in the coil as a function of time? In
which direction does the current flow?
Magnetic forces can be used to accelerate projectiles to very high speeds in a so-called railgun. In the simplified version shown below, a voltage source drives current down two parallel ideal wires to a section of metal in contact with both wires. The metal has a resistance 0.6 mΩmΩ and weights 6 grams. We assume that the contacts between the wires and the section of metal are friction-less and that the metal can slide along the wires for a total distance of 1 m before exiting the railgun as a projectile. Our goal is to calculate what voltage that will cause the metal projectile to leave the railgun at the speed of sound (343 m/s), assuming it starts from rest.
First, what constant force (in N) will accelerate the rod to the speed of sound in 1 m? Give your answer to 3 significant digits.
Next, which voltage V will generate the necessary current to create this constant force? Give your answer to 3 significant digits.
Consider a transformer, used to recharge rechargeable flashlight batteries, that has 500 turns in its primary coil, 4 turns in its secondary coil, and an input voltage of 120 V.
Note that n = 4
(a) Given that the input current I(p) is 0.0256 A, to produce a 3.2 A output current, convert 0.0256 A to milliamps.
I(p) =
Part (c) What is the power input, in watts? (Explain thoroughly whether or not you use amps or milliamps for this calculation)
