south
magnetic field is
stronger
the
closer
it is to the magnet
magnetic material:
Nickel
Cobalt
Iron
Steel
NCIS
Permanent
magnets - A magnet that always has a magnetic field
Magnetically
soft
- loses magnetism very quickly eg
Nickel
,
Iron
Magnetically
hard
- harder to lose magnetism eg
steel
Electromagnetism
- Using current to product magnetic field
Field lines always
perpendicular
to current
Solenoid
- A coil of wire that produces a magnetic field when
current
is passed through it. Inside is
strong
and
uniform
ways to increase electromagnet strength:
Increase
current
Increase number of
turns
Decrease distance between each
loop
