## How do you find the repulsive force of a magnet?

## How do you find the repulsive force of a magnet?

Formula used: We are using Coulomb’s law of magnetism. According to this law, Attraction or repulsive force between two poles are given as \[F = \dfrac{{{\mu _0}}}{{4\pi }}\dfrac{{{m_1}{m_2}}}{{{r^2}}}\].

**How do you calculate magnetic force?**

F=ILBsinθ where θ is the angle between the wire and the magnetic field. The force is perpendicular to the field and the current. The equivalent formula for the force on a moving charged particle of charge q and velocity v is F, equals, q, v, B, sine, theta,F=qvBsinθ, with the force perpendicular to field and velocity.

**Is magnetic force a repulsive force?**

magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion. It is the basic force responsible for such effects as the action of electric motors and the attraction of magnets for iron.

### How strong is magnetic repulsion?

The attraction as well as the repulsion of magnets decrease significantly with increasing distance. When two equal magnets touch each other, the attraction between two unequal poles is 5-10% stronger than the repulsion of equal poles. That is due to the alignment of the molecular magnets in a magnet.

**What is the force between two magnetic poles?**

The force of interaction between two stationary magnetic poles is inversely proportional to the square of the distance between the two poles. The force between the two poles acts along the straight line joining the two poles. Like poles repel each other and the unlike poles attract each other.

**How much repel force does a magnet have?**

When two equal magnets touch each other, the attraction between two unequal poles is 5-10% stronger than the repulsion of equal poles. That is due to the alignment of the molecular magnets in a magnet….Concrete calculation example.

Distance | Attraction | Repulsion |
---|---|---|

4 cm | 5 kg | 5 kg |

#### What is the force of repulsion?

Repulsion is’ a movement between two charges that are identical or similar. The force of two electrons between them (negative charge). Attraction: Attraction is’ a force between two charges that are different or different. ‘ The two charges of a different type draw against one another.

**What is the law of magnetic attraction and repulsion?**

The law states that the force of attraction or repulsion between two magnetic poles is directly proportional to the product of the strengths of the poles and inversely proportional to the square of the distance between them.

**What is the force of attraction or repulsion of magnetic materials?**

The force of attraction or repulsion of magnetic materials.

## What is Coulomb’s law of magnetic force?

The Coulomb force is inversely proportional to the squared distance between the magnetic poles Q1 and Q2, repulsive between like poles (N–N, S–S) and attractive between unlike poles (N–S).

**What are the two magnetic forces?**

The two types of magnetic forces are attractive magnetic forces and repulsive magnetic forces. The former pulls two magnetic substances towards each other and the latter pushes them away from each other.

**Is magnetic repulsion or attraction stronger?**

The attraction between magnets is a little stronger than the repulsion. That is due to the alignment of the molecular magnets in the magnet.

### What is an example of repulsive force?

Repulsive force (magnetism) between magnets of opposite orientation. A compressed material repelling bodies on both sides, e.g. according to Hooke’s law. Repulsive force (biology), associated with involuntarily vomiting, as in response to ingestion of a toxin.

**What is the force of repulsion between two charges of 1c?**

F=rKQQ=((10))9×10=9×103N.

**What is the law of magnetism MBA?**

(a) Gauss’s law for magnetism states that the total magnetic flux through a closed surface is always zero. Mathematically, it can be described as . It is the same as saying that monopoles can’t exist.

#### What is the formula for the force acting on a magnet?

F = k q 1 q 2 r 2. It’s just that the pole is not isolated. Still, this can be approximated if magnets are thin and long compared to their separation. The more complicated formula given by Erik is simply due to adding the forces between all 4 poles.

**What is the force of magnetic repulsion on a particle?**

It depends onthe charge (q) of the particle, the velocity (v), and the magnetic field (B), and the force on a negative charge is opposite to that on a positive charge.

**What is another name for magnetic repulsion?**

Alternative Titles: magnetic attraction, magnetic repulsion Magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion. It is the basic force responsible for such effects as the action of electric motors and the attraction of magnets for iron.
