What are the 3 ways you can increase the strength of an electromagnet? The three ways by which the strength of an electromagnet can be increased are: By increasing the current flowing in the coil. By increasing the number of turns in the coil. By inducing the length of the air gap between the poles.
What are electromagnets how its strength can be changed class 10? An electromagnet can be defined as a magnet which functions on electricity. Unlike a permanent magnet, the strength of an electromagnet can be changed by changing the amount of electric current that flows through it. If the current flow is cut, the property of magnetism ceases to exist.
What is an electromagnet How can you increase the strength of an electromagnet Class 7?
- Increasing he strength of the current passing through the coil, the greater the current, the greater the strength;
- Increasing the number of turns in the coils, the greater the number of turns, the greater the strength;
What is an electromagnet Class 7 short answer? Answer: An electromagnet is a coil of insulated wire wound around a piece of a magnetic substance such as soft iron. The magnetic substance acts as a magnet as long as the current flows in the wire.
