20.1Magnetic fields and field lines
A magnetic field is a region where a magnet, a moving charge or a current feels a force.
Frayer Model1 Q, 12 marks (topic)4 checkstab 1
20.2Force on a current-carrying conductor
Put a current in a magnetic field and the wire is pushed sideways.
Connect-Extend-Challenge3 Q, 36 marks (topic)4 checkstab 3
