1. Identify the factors that affect the magnitude of the induced emf and the magnitude and direction
of the induced current (Faraday's Law)
2. Compare and contrast electrostatic electric field and non-electrostatic/induced electric field
3. A square loop of wire 10.0 cm on a side is in a 1.25 T magnetic field B. What are
the maximum and minimum values of flux that can pass through the loop?
Approach
The flux is given by Eq. 2 (B = BA cos e). It is a maximum for e = 0°, which occurs when
the plane of the loop is perpendicular to B. The minimum value occurs when e = 90° and
the plane of the loop is aligned with B.
4. A coil of wire is situated in a 0.5 T uniform magnetic field. The area of the coil is
2.0 m2. (a) What is the magnetic flux if the angle between the magnetic field and
the normal to the surface of the coil is 60°? (b) After 5 s, the magnetic field is
nowparallel to the normal to the surface. What is the induced emf?

Approach
(a) The angle between the magnetic field and the normal to the surface of the
coil is 60°
O Storage
(b) The angle between the magnetic field and the normal to the surface of the
coil is 0°, because the magmetic field is now parallel to the normal surface
(see Fig. 3).
5. Calculate the magnitude of the induced emf when the magnet is thrust into the coil, given
the following information: the single loop coil has a radius of 6.00 cm and the average
value of B cos 0 (this is given, since the bar magnet's field is complex) increases from
