Consider a conducting rod of length 28 cm moving along a pair of rails, and a magnetic field pointing perpendicular to the plane of the rails. At what speed (in m/s) must the sliding rod move to produce an emf of 1.1 V in a 1.25 T field?

True or False A moving charge entering a magnetic field parallel to the field will move in a straight line. A man whose resistance is 10,000 Ω has 120 volt potential difference across his body.  This would cause a fatal shock. Adding resistors to a parallel circuit decreases the equivalent resistance. The resistance of a resistor increases with decreased temperature The terminal voltage (V) of a battery is always less than its EMF (ξ). The electric field E is a scalar but the electric potential V is a vector.

Two moving rods of equal lengths (1.20 m) are moving as shown in the figure. The speed v1 = 1.10 m/s and the speed v2 = 2.00 m/s. If the magnetic field is uniform with a magnitude of 0.60 T, what is the magnitude of the average emf in the loop?

A square, single-turn coil 0.27 m on a side is placed with its plane perpendicular to a constant magnetic field. An EMF of 19 mV is induced in the winding when the area of the coil decreases at a rate of 0.11 m2/s. What is the magnitude of the magnetic field?

An emf is induced by rotating a 1107 turn, 20.0 cm diameter coil in the Earth's 3.53 x 10-5T magnetic field. What average emf is induced, given the plane of the coil is originally perpendicular to the Earth's field and is rotated to be parallel to the field in 10.0 ms?

Suppose you rotate a 1000 turn, 19 cm diameter coil in the Earth’s 5.00 × 10-5 T magnetic field. What is the peak emf generated in V, given the plane of the coil is originally perpendicular to the Earth’s field and is rotated to be parallel to the field in 8.5 ms?
