A long straight wire lies on a horizontal table and carries an ever-increasing current northward. Two coils of wire lie flat on the table, one on either side of the wire. When viewed from above, the induced current circles
A)
clockwise in both coils.
B)
counterclockwise in both coils.
C)
clockwise in the east coil and counterclockwise in the west coil.
D)
counterclockwise in the east coil and clockwise in the west coil.
E)
no emf is induced in either coil.
Question 2
A wire of length L carrying a current I is placed in a magnetic field. The direction of the magnetic field is opposite the direction of the current. In this situation, the wire experiences a maximum force.
Indicate whether the statement is true or false
To reverse the direction of operation, the polarity of the current through the motor is reversed.
