What can magnets only do?

When are the field lines always strongest?
Stronger near the poles since the field lines are very close together
What way are the field lines
Show the magnetic field lines on the earth
What does a electric current create?
A temporary Magentic Field
What does the right hand grip tell us?
The field direction
The thumb points in the…
direction of the current flow
What does a Solenoid Field do?
Carries Current and therefore creates field lines.
