## Does magnetic field lines always form closed loops?

Magnetic field-lines form closed loops which never begin or end. Thus, magnetic field-lines behave in a quite different manner to electric field-lines, which begin on positive charges, end on negative charges, and never form closed loops.

Why do magnetic field lines create closed loops?

Magnetic lines form continuous closed loops because magnetic monopole does not exist in nature. We always find magnetic poles – North and South pole which are coupled together in such a way that field lines originating from one pole ends at the another loop, forming a closed loop.

### Do field lines form closed loops?

The main reason behind the electrostatic field lines not forming a closed loop is that the no electric field line exists inside the charged body. Therefore, we say electrostatic field lines never form closed loops.

Are the magnetic field lines closed loops explain?

Magnetic field lines are closed curves as they propagate from the North pole outside the magnet’s body to the magnet’s body and from the south pole to the north pole inside the magnet’s body. Hence, the magnetic field lines are closed.

## Why can’t magnetic field lines cross?

Magnetic field lines originate from the north pole and merge at the south pole. As the distance between the poles tends to increase, magnetic line density reduces. Magnetic lines do not intersect with one another. The magnetic lines strength is the same throughout, and it is proportional to how near the lines are.

Which magnetic field is the strongest?

The magnetic field generated by any magnet is always strongest at either pole. The magnetic force is equally as strong at both the north and south pole.

### Are magnetic lines of force always closed?

Magnetic field lines are continuous, forming closed loops without beginning or end. They go from the north pole to the south pole.

What is Closed Loop?

: an automatic control system in which an operation, process, or mechanism is regulated by feedback.

## Why can’t electric field lines cross?

Electric field lines cannot cross. This is because they are, by definition, a line of constant potential. The equipotential at a given point in space can only have a single value. If lines for two different values of the potential were to cross, then they would no longer represent equipotential lines.

Are magnetic flux lines always closed?

### Why do magnetic field lines always form closed loops?

Magnetic field lines always form closed loops because of the presence of magnetic dipoles and absence of magnetic monopoles in nature. We will always find the a magnetic poles (north and south) as couples so the field lines beginning from one end (pole) have to end at the other.

Do electric field lines always form closed loops?

The electric field lines can never form closed loops , as line can never start and end on the same charge. These field lines always flow from higher potential to lower potential.

## Are the magnetic field lines open or closed curves?

(b) Magnetic field lines are closed continuous curves. They diverge from the north pole of a bar magnet and converge its south pole. Inside the magnet they move from south pole to north pole.

Are magnetic field lines always closed?

Magnetic field-lines form closed loops which never begin or end . Thus, magnetic field-lines behave in a quite different manner to electric field-lines, which begin on positive charges, end on negative charges, and never form closed loops.
