1. Increase the number of turns in the coil: Increasing the number of turns in the coil will increase the amount of magnetic field produced, making the electromagnet stronger.
2. Increase the current in the coil: Increasing the current flowing through the coil will increase the strength of the magnetic field produced, which will make the electromagnet stronger.
3. Use a stronger core material: Using materials with higher magnetic permeability such as soft iron, cobalt or nickel can increase the strength of the magnetic field produced, which in turn will make the electromagnet stronger.
You start with the electromagnet pictured. Name three ways you can increase the strength of this electromagnet.
