Physics 2: Electromagnetic Induction
A magnetic field increases with time as described by the function, B(t) = 4 + 6t. Given a coil with 880 turns, N = 880, and an area A = (.05m), find the induced voltage in the coil.
Find the direction of the induced current in the resistors.
A.
The magnet is being pulled away in the direction of the arrow
B.
When the current, I, is increasing with time.
A metal rod is moved to the right through a magnetic field. A charge separation is induced as shown below. Determine the direction of the magnetic field.
The circuit below is set in a uniform magnetic field that is going into the page. The circuit is attached to a moving conducting bar, shown in blue, below. The result is the circuit has a fixed length L and an increasing width of X. Find the induced current as a function of the velocity of the bar in the direction shown.
