What type of core is best for electromagnets?

Back

Iron is the best core material for electromagnets because it enhances the magnetic field.

What is a parallel circuit?

Back

A parallel circuit is a type of electrical circuit where multiple paths exist for current to flow.

Front

What is a series circuit?

Back

A series circuit is a type of electrical circuit where components are connected end-to-end, so the current flows through each component in turn.
