Question

Which relations below regarding magnetic field and electric field lines are true? 1. Magnetic field lines never begin nor end but always loop around on themselves while electric field lines begin at positive charges and end at negative charges. 2. Magnetic field lines never begin nor end but always loop around on themselves while electric field lines begin at negative charges and end at positive charges. 3. Magnetic field lines begin at north poles and end at south poles while electric field lines loop around on themselves. 4. Magnetic field lines begin at south poles and end at north poles while electric field lines loop around on themselves. 5. Magnetic field lines come out of north poles outside the magnet and into north poles inside the magnet. Magnetic field lines go into south poles outside the magnet and out of south poles inside the magnet. Electric field lines begin at positive charges and end at negative charges.

Answer 1

Answer:

Options 1 and 5 are correct

Explanation:

Magnetic field lines can never cross, the field is unique at any point in space. Magnetic field lines are continuous, forming closed loops without beginning or end. They go from the north pole to the south pole.

Magnetic field lines form closed loops but do not intersect.

Electric field lines originate at the positive charges and terminate at the negative charges. They move in a straight line and are parallel. Electric field lines neither form closed loops nor intersect.

Since, magnetic field lines form closed loops and move from North to South pole, they come out of north poles outside the magnet and into north poles inside the magnet, they also go into south poles outside the magnet and out of south poles inside the magnet.
