In this lesson, we will learn how to calculate the self-inductance of a conducting loop and the mutual inductance of a pair of conducting coils.
Students will be able to
Q1:
A loop of wire increases the current that it carries by 180 mA. The change in magnetic flux produced by the change in current is 0.77 Wb. What is the self-inductance of the loop? Give your answer to one decimal place.
Q2:
A loop of wire has a self-inductance of 0.36 H. The current through the loop is 420 mA. What is the magnetic flux produced by the current? Give your answer to two decimal places.
Q3:
A loop of wire has a potential difference of 1.2 V across it. The loop has a self-inductance of 125 mH. How much time is required for the loop to increase the current through it by 0.25 A? Give your answer to two decimal places.
