Current carrying wire deflects compass –
connection between electricity and
magnetism
Electromagnetism
Ampere
Current carrying wires create circular
magnetic fields around the wire. Direction of
the field depends on the direction of the
current.
Solenoid
Coil of wire – each loop contributes to
the total magnetic strength

•Ferromagnetic material inserted in solenoid
•Domains are aligned by the magnetic field
•Stronger magnet
