Question

A) By substituting in the base units show how the units for Faraday's law reduce to be equivalent.

emf(volts) = rate of change of magnetic flux (Tesla - meters^2 per second)

V = Tm²/s

B) A common way to induce an emf in a conductor is to rotate a coil of wire in a uniform magnetic field. If you have circular coil of radius 1.27 cm in a 2.0 T field, what is the maximum flux?

	a.	1.57x104 T m2
	b.	25.4 T/m2
	c.	1.01x10-3 T m2
	d.	0.101 T m2
	e.	0.0254 T/m2

C) A common way to induce an emf in a conductor is to rotate a coil of wire in a uniform magnetic field. If you have circular coil of radius 1.27 cm in a 2.0 T field, what is the minimum flux?

	a.	2.25 x10-5 T
	b.	4.13 x10-7 T m2
	c.	0 T m2
	d.	1.01x10-3 T m2
	e.	3.45 x 102 T m2

D) A simple loop of wire enclosing an area of 12 cm² moves steadily from an area with no magnetic field to being completely in a field of 4.0 T. The transition takes 3.0 seconds. What potential is induced in the coil?

	a.	14.4 V
	b.	3.0 mV
	c.	0.4 mV
	d.	1.6 mV
	e.	16 V
