Formula used:
We are using Coulomb’s law of magnetism. According to this law, Attraction or repulsive force between two poles are given as \[F = \dfrac{{{\mu _0}}}{{4\pi }}\dfrac{{{m_1}{m_2}}}{{{r^2}}}\].
Also to know is, what are the forces acting on the lower magnet?
The magnet’s weight and the magnetic force attracting it to the lower magnet. Two magnetic forces: one attracting it to the lower magnet and another pushing it away from the lower magnet.
If it moves in the other direction, then the v value must be negative. These two particles repel each other if the magnetic forces determined by their respective magnetic fields between them cancel each other out by pointing in different directions away from one another.
Subsequently, what force is a magnetic force?
What is the magnetic force? The magnetic force is a consequence of the electromagnetic force, one of the four fundamental forces of nature, and is caused by the motion of charges. Two objects containing charge with the same direction of motion have a magnetic attraction force between them.
What is attraction and repulsion of a magnet?
When two magnets are moved close to each other, they either attract or repel each other. The opposite poles of magnets attract, whereas the similar poles of magnets repel when they are pulled towards each other. Attraction or repulsion of the magnets depends on the direction of the poles facing each other.
What is magnetic force example?
This force causes the magnets to attract or repel one another. Examples of magnetic force is a compass, a motor, the magnets that hold stuff on the refrigerator, train tracks, and new roller coasters. All moving charges give rise to a magnetic field and the charges that move through its regions, experience a force.
What is magnetic repulsion?
When two opposite magnetic poles are close, they attract each other. When like poles are pushed together, there is a force of repulsion. The rule for magnets is that like poles repel and unlike poles attract.
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 formula for magnetic force between two magnets?
Hint: We know that the force between two magnetic poles is classically given by the equation $F = \dfrac{{{\mu _0}{m_1}{m_2}}}{{4\pi {r^2}}}$ . Use this equation for when the distance increases by $n$ times and when the distance reduces by $\dfrac{1}{{{n^{th}}}}$ times.
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.
