Self induction

Determine the inductance of the coil if a 5 V self-induction EMF occurs at a rate of change of current of 10 A / s.

• 5 H

• 0,5 H

• 2 H

• 0,2 H

An induction current is shown in the coil contained in the alternating magnetic field, the direction of which is shown in the figure. How does the magnetic flux that permeate the circuit change?

• Does not change;

• increases;

• decreases;

• periodically increases and decreases.

Passing a current through a solenoid will produce

• a magnetic field
• an electric field
• a current field
• nothing is produced

13.2 If a magnet is pushed into a coil, voltage is induced across the coil. If the same magnet is pushed
into a coil with twice the number of loops,

• a. one-half as much voltage is induced.
• b. the same voltage is induced.
• c. twice as much voltage is induced.
• d. four times as much voltage is induced.
