You can increase the strength of an electromagnet by

using a stronger ferromagnetic material for the core

changing the position of the compass

adjusting the magnetic declination

You can increase the strength of an electromagnet by

decreasing the current in the solenoid

The north and south poles of a solenoid change with

the type of material in the core

the number of loops in the coil

the tightness of the loops in the coil

Both solenoids and electromagnets produce magnetic fields using

electric current and coiled wires

coiled wires and ferromagnetic core

When a wire with a current is placed in a magnetic field

electrical energy is transformed into mechanical energy

kinetic energy is transformed into potential energy

electrical energy is transformed into sound and light

solar energy is transformed into light and heat

An electric motor uses

electrical energy to produce mechanical energy

visible light to produce mechanical energy

mechanical energy to produce sound

mechanical energy to produce electricity

An electric generator transforms

mechanical energy into electrical energy

electrical energy to mechanical energy

electromagnetic energy to mechanical energy
