## What are the similarities and differences between gravitational electric and magnetic field?

They both have a point source, and with this point source they both have a field intensity that is proportional based on the inverse square law. Both exert force from a distance with no contact. -you can’t shield yourself from gravitational force, but you can from an electric force with insulation, etc.

## What is the major difference between gravitational field and magnetic field?

These two are completely different phenomena of physics. Gravity acts as a force between two masses while magnetism acts as a force between magnetic poles (which is just an idealization of a region of space where magnetic flux seems to get higher, but it really is a force that acts upon moving electric charges).

## What are the similarities between electric and magnetic fields?

Similarities between magnetic fields and electric fields: Electric fields are produced by two kinds of charges, positive and negative. Magnetic fields are associated with two magnetic poles, north and south, although they are also produced by charges (but moving charges). Like poles repel; unlike poles attract.

## What are two differences between gravitational and electromagnetic fields?

Gravity is a weak force, but has only one sign of charge. Electromagnetism is much stronger, but comes in two opposing signs of charge. … Gravitational waves, similarly, are generated by the bulk motion of large masses, and will have wavelengths much longer than the objects themselves.

Gravity and magnetism are not the same thing. In fact, they are completely separate forces. Gravity is a force that acts between any two objects with mass. … In some materials (permanent magnets) the domains can all be lined up so you get really big magnetic forces.

## Do magnetic fields have mass?

magnetic fields are produced by charged particles in motion, and depend on the charge and velocity of these particles, but not on their mass.

## What is the symbol of magnetic field?

Index to magnetic terms & units in the SI

Quantity name Quantity symbol Quantity symbol
magnetic field strength H Φ
magnetic flux density B χρ
magnetic moment m J
magnetic susceptibility χ M

## What does electricity and magnetism have in common?

3) Electricity and magnetism are essentially two aspects of the same thing, because a changing electric field creates a magnetic field, and a changing magnetic field creates an electric field. (This is why physicists usually refer to “electromagnetism” or “electromagnetic” forces together, rather than separately.)

## What are the similarities and differences between electric motor and generator?

The Difference Between Electric Motor and Electric Generator in Tabular Form

Electric Motor Electric Generator
The shaft of the motor is driven by the magnetic force generated between the armature and the field. In electric generators, the shaft is attached to the rotor and is driven by the mechanical force.

## What is the major difference between electric charges and magnetic fields?

In the electric field, the like charges repel each other, and the unlike charges attract each other, whereas in a magnetic field the like poles repel each other and the unlike poles attract each other.

## What are two similarities and differences between the electric force and gravitational force?

Electric vs Gravitational Force

Similarities Differences
Inverse Square Laws Electric forces are stronger on small scales while Gravitational forces are stronger on a massive scale
Both have fields Electric force can be both repulsive and attractive but gravity only attracts

## What are two applications of electromagnetic fields?

Electromagnetism serves as a basic principle of working for many of the home appliances in household applications. These applications include lighting, kitchen appliances, air conditioning systems, etc. The most dominant use of power in homes as well as commercial buildings is lighting systems.

## What are the similarities between electric force and gravitational force?

Similarities between electrostatic and gravitational forces: Both act in a vacuum. Both are central and conservative. Both obey an inverse-square law .
