Is magnetic field frame dependent?

Is magnetic field frame dependent?

Yes, magnetic field is dependent on the frame of reference of the observer. Consider a magnetic field originated due to the motion of a charged particle. As the motion of any object is frame dependent, the velocity of the charged particle is dependent on the frame of reference.

Which direction is relative to magnetic field?

Magnetic fields exert forces on charged particles in motion. The direction of the magnetic force F is perpendicular to the plane formed by v and B as determined by the right hand rule.

What is relative motion in magnetism?

It is the relative motion between the two that is important, so either a conducting wire can be moved through a stationary magnetic field, or a magnet can be moved near a stationary conducting wire.

Can there be electricity without magnetism?

You can generate electricity by many methods without magnetic fields: chemical (batteries and fuel cells), solar (photovoltaic cells), and thermal (thermocouples, Seebeck effect). There are many biological generators as well (nerve and muscle tissues in your body) in addition to the obvious electric eels.

Can there be a magnetic field without an electric field?

No you can have a magnetic field without an electric field. Consider a rod with an equal number of positive and negative charges (such that they are equally spaced). Let the positive move to the left with speed v and the negative to the right with speed v. This will result in a magnetic field but no electric field.

Does the Earth have a magnetic field?

In a sense, yes. The Earth is composed of layers having different chemical compositions and different physical properties. The crust of the Earth has some permanent magnetization, and the Earth’s core generates its own magnetic field, sustaining the main part of the field we measure at the surface.

Is magnetic field from north to south?

Magnetic field lines outside of a permanent magnet always run from the north magnetic pole to the south magnetic pole. The earth spins around the geographic poles, but magnetic compasses point to the magnetic poles.

Why all motion are relative?

Physical Science all motion is relative because every object at rest is also in motion and every object motion is in rest and these both term are related to each other… and these all depends on reference point.

What is relative motion in friction?

Definition. Friction is a catchall word that refers to any force that resists relative tangential motion (or intended motion). “Relative tangential motion” is a fancy way to say “slipping” or “sliding”. Its direction is opposite the relative velocity (or intended velocity).
