Concept explainers
True or False? The strength of the magnetic field in an electromagnet increases with an increase in the number of turns of wire and the current flowing through them.
Whether the given statement is true or false.
Answer to Problem 1RQ
The correct answer is TRUE.
Explanation of Solution
Given information:
The strength of the magnetic field in an electromagnet increases with an increase in the number of turns of wire and the current flowing through them.
The magnetic field exists around every magnet. By placing an iron bar inside the current carrying wires an electromagnet is produced. The strength of the magnetic field of these electromagnets is directly proportional to the number of turns of wire and the current flowing through them. So the above statement is true.
