Does the number of turns of wire in a electromagnet affect its strength
Lets start off with what Electromagnets are.
Electromagnets are used to lift large masses of magnetic material
To create a strong field it can be produced if a wire is wrapped around a strong iron core and a current is passed through the wire...
For an electromagnet to lift something heavy it has to have a strong field.
The strength of an electromagnet can be increased by increasing the number of loops around the iron core, every coil of wire increases the "magnetic flux density"strength of your magnet, so the number of turns of wire affects the electromagents strength.
