Making Magnets Flashcards
Compass
A device with lines up with the earth’s magnetic field
Constructing a compass
A long, thin strip of magnetic material that is free to rotate
Drawing Magnetic fields
Place a compass nearby and connect lines to show the direction it points in
Electromagnet
A magnet created with coils of wire with current through them
Electromagnet Parts
A magnet with created coils of wire with current flowing through them
Solenoid
The shape formed when wires are coiled in a cylinder
Ways to Increase Electromagnet Strength
Increase current, increase coils of wire or use an iron core
Current - carrying conductor
A piece of conducting material that current flows through
Equation of an electromagnet force
F = B x I x L Force = mag field strength x current x length of wire
motor effect
a current through a conductor in a mag field recieves a force
