## How is mass related to magnetic field?

Gravitational fields are determined only by the mass ( or mass-energy) of a body. magnetic fields are produced by charged particles in motion, and depend on the charge and velocity of these particles, but not on their mass. Magnetic fields are ‘polar’ fields with a North and South polarity.

## What is Q in F qvB?

The equation is given by F = q v × B or F = qvB sin θ, where q is the charge, B is the magnetic field, v is the velocity, and θ is the angle between the directions of the magnetic field and the velocity; thus, using the definition of the cross product, the definition for the magnetic field is.

**What is magnetic field class 10th?**

The area around a magnet where the influence of a magnet can be experienced is called magnetic fields. It has both magnitude and direction and the magnetic field and its field and direction are represented by magnetic lines of force.

### What is magnetic field and its unit?

The SI unit for magnetic field is the Tesla, which can be seen from the magnetic part of the Lorentz force law Fmagnetic = qvB to be composed of (Newton x second)/(Coulomb x meter). A smaller magnetic field unit is the Gauss (1 Tesla = 10,000 Gauss).

### Does magnetic field depend on mass?

It is not directly related. The magnetic field created by a particle is calculated from its electric charge, position, and velocity, according to Maxwell’s equations. Of course a particle’s position and velocity would probably be different if its mass were different, so there is an indirect relationship.

**Does magnetic field increase with mass?**

Yes. When you push two opposing magnets together you add energy. So the mass increases.

#### What is tesla per ampere?

One tesla (1 T) is defined as the field intensity generating one newton (N) of force per ampere (A) of current per meter of conductor: T = N × A-1 × m-1 = kg × s-2 × A-1. Certain other non-SI units, like Gauss (G), are still occasionally used. A magnetic field of one tesla is quite strong.

#### What is Q in magnetic field?

If a charge q is moving with uniform velocity v parallel to the direction of a uniform magnetic field B, it experiences no force. Your thumb points in the direction of the vector product v × B. If q is positive then this is the direction of F. If q is negative, your thumb points opposite to the direction of F.

**What is E F Q?**

E = F / q. The electric field strength (E) is defined as the amount of force exerted upon a test charge per unit of charge on the test charge (q). That is, E = F / q. The electric force (F) depends upon a number of variables as described by Coulomb’s law.

## What is the formula for magnetic field size?

Magnetic Field Formula. The magnetic field formula contains the (constant^{mu_{0}}). This is known as permeability of free space and has a (value^{mu}_{0}) = (4pi times 10^{-7} (T cdot m)/ A). Besides, the unit of a magnetic field is Tesla (T). Magnetic field magnitude = (frac{(permeability of free space) (current magnitude)}{2pi (distance)})

## What is magnetmagnetic force?

Magnetic force can be defined as: The magnetic force between two moving charges may be described as the effect exerted upon either charge by a magnetic field created by the other.

**What is the magnetic field?**

Also, we have seen how the same side of the magnets repels each other. But, the magnetic field is the field of current that attracts and repels the magnet. Furthermore, in this topic, you will learn about the magnetic field, magnetic field formula, its derivation, and solved examples.

### How do you find the magnetic force?

The magnetic force depends upon the charge of the particle, the velocity of the particle and the magnetic field in which it is placed. The direction of the magnetic force is opposite to that of a positive charge. The magnitude of the force is calculated by the cross product of velocity and the magnetic field, given by q [ v × B ].
