Electric field lines:
Originate on positive charges and terminate on negative charges.
Originate on negative charges and terminate on positive charges.
Can be originated on either charges but terminates only on negative charges.
Form closed loops
- 2. Multiple Choice
Based on Maxwell starting points:
•Magnetic field lines :
always form closed loops – they do not begin or end anywhere.
they can form closed or open loops – they begin at specific point but end anywhere.
originate on south poles and terminate on north poles.
magnetis can be found as separate poles
- 3. Multiple Choice
One of Maxwell's starting points was
