磁力,磁場.磁力線.磁場線

1)磁力同磁場有咩唔同?
Magntic force (磁力) is the force experienced by a magnetic pole or a moving charge in a magnetic field(磁場) . Hence, the presence of magnetic field give rise to magnetic force.
2)磁場係咪力,點解?
No. A field is NOT a force. A field would give rise to a force in the presence of magnetic poles or moving charges.


3)磁力線同磁場線有咩分別?
Magnetic line of force (磁力線) and magnetic field lines (磁場線) basically means the same. It is called "line of force" because field lines are defined using the "direction of force" that will be experienced by a north magnetic pole when it is placed in the field.
