Is magnetic field equal to electric field?

They are two different fields with nearly the same characteristics. Therefore, they are inter-related in a field called the electromagnetic field….Comparison chart.

	Electric Field	Magnetic Field
Nature	Created around electric charge	Created around moving electric charge and magnets

What is the relation between velocity and magnetic field?

The magnetic force is perpendicular to the velocity, and so velocity changes in direction but not magnitude. Uniform circular motion results. The component of the velocity parallel to the field is unaffected, since the magnetic force is zero for motion parallel to the field.

How does a magnetic field compared to an electric field?

Both electric and magnetic fields are the consequence of the attraction and repulsion of electric charges. However, a magnetic effect is caused by moving electric charges while an electric field is caused by stationary charges.

Why is magnetic force perpendicular to velocity?

The superficial answer is simply that the Lorentz (magnetic) force is proportional to v×B, where v is the particle velocity and B is the magnetic field. Since the vector cross product is always at right angles to each of the vector factors, the force is perpendicular to v.

What is the relationship between the electric fields and magnetic fields of electromagnetic waves?

But in an EM wave, the electric field and magnetic field carry the same energy. So in an EM wave, the magnitude of the electric field is proportional to the magnitude of the magnetic field, and the proportionality constant is c, the speed of light!

What is the basic difference between magnetic field and electric field assertion?

Assertion: Basic difference between electric lines and magnetic lines of force is that former are discontinuous and the latter are continuous. Reason: No electric lines of forces exit inside charged conductor but magnetic lines do exist inside magnet.

Why is magnetic field perpendicular to electric field?

Originally Answered: Why are electric and magnetic fields perpendicular to each other? The magnetic field is along the axis of electrons spin, meaning it always has to be perpendicular to the movement of the electrons, it’s a nature of the behavior of charges and waves. The reason for this is the Faraday’s law.

Is magnetic field always perpendicular to velocity?

The force exerted on a charge moving in a magnetic field is always perpendicular to both the velocity and the field. Any force perpendicular to the velocity can not change the speed (or the kinetic energy). All it can do is make the charge change direction.

Which is stronger magnetic field or electric field?

Magnetic forces are much stronger than electric forces when you compare them at the saturation and breakdown strengths of materials. That is the reason why all practical electromechanical conversion devices use magnetic forces.

How does a magnetic field affect the direction of velocity?

If velocity has a component along B, this component remains unchanged as the motion along the magnetic field will not be affected by the magnetic field. The motion in a plane perpendicular to B is as before a circular one, thereby producing a helical motion. However, the electric field in y-direction imparts acceleration in that direction.

What is the difference between electric and magnetic field?

Magnetic Field. Electric field : 1) A distribution of electric charge at rest creates an electric field E in the surrounding space. 2) The electric field exerts a force F E = q E on any other charges in presence of that field. Magnetic field: 1) A moving charge or current creates a magnetic field in the surrounding space (in addition to E).

What is the ratio of electric field strength over magnetic field strength?

When working in SI units, the ratio of electric field strength over magnetic field strength in EM radiation equals 299 792 458 m/s, the speed of light c. However, the numerical value for c depends on the units used. When working in units in which the speed of light c = 1, one would conclude that both fields are equal in magnitude.

How do you find the force of a magnetic field?

In the case of a magnetic field, you have 3 vectors each perpendicular to each other: First one is the field itself. The second one is the velocity of the proton. Force is equal to F → = Q v → B →.
