Those who are looking for an answer to the question «One of the differences between electric and magnetic fields is that magnestic files lines always form closed loops?» often ask the following questions:

👉 Do electric and magnetic fields always form closed loops?

Magnetic fields do, because there's no such thing as an isolated magnetic "pole", and a magnetic line always starts and ends at opposite poles of the same magnetized object. But electric fields don't. You can easily have a bundle of isolated positive charge over here and a bundle of isolated negative charge over there, whereupon the lines of the electric field start on one bundle and end on the other bundle. But electric field lines can also exist in closed loops, and they do that in radio waves, where the electromagnetic field propagates with an electric field component and a magnetic field component, and they both form closed loops.

👉 Can electric field lines form closed loops?

For a positive charge, the electric lines of force will be radially outward, and for a negative one, they will be radially inward. Also, electric lines of force originate from a positive charge and terminate at a negative charge. Thus, if we con...

Why electric field lines do not form closed loops meritnation?

On the the left-hand side is a closed line integral of the electric field. Since that integral isn’t always zero, the electric field in this case is non-conservative. If that electric field existed without the complementary magnetic field this would be a violation of conservation of energy, but the relationship between the two causes that to not be the case.

What are the main differences between magnetic and electric fields?

The absence of magnetic charge in Physics is the reason why a magnet must always have a North and a South pole, while an electric field can come from a single point in space (an electric monopole). Another important difference is in the force a charged particle experiences in each type of field.

Are magnetic fields electric fields found?

Magnetic Field A magnetic field is a vector field in the neighbourhood of a magnet, electric current, or changing electric field, in which magnetic forces are observable. A magnetic field is produced by moving electric charges and intrinsic magnetic moments of elementary particles associated with a fundamental quantum property known as the spin.

Do electric fields create magnetic fields?

The area around the magnet where attractive forces or repulsive forces are exhibited by the poles of the magnet is called magnetic field. When electric charges move across space or an electrical conductor, a magnetic field is induced due to its motion. Comparing the Two Fields . 1.

Why electric field lines does not form close loops?

Answer The field lines starts (or diverges) from the positive charge and terminate (or converges) on negative charge. If the electric field lines form closed loop, these line must originate and terminate on the same charge which is not possible because electric field lines always moves from positive to negative.

How are magnetic fields like electric fields?

4. As you pointed out correctly, a magnetic field is created by a moving charge (current) with respect to the observer. If the charge is at rest with respect to the observer, only an electric field is seen. The fact that a magnetic field looks the way it does can be derived by making use of a Lorentz transformation.
