1:n4. 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.
Also know, how is the force of attraction or repulsion between two magnetic poles determined?
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.
In this way, 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.
What force does a magnet use?
What forces do magnets have?
Magnetic forces are non contact forces; they pull or push on objects without touching them. Magnets are only attracted to a few ‘magnetic’ metals and not all matter. Magnets are attracted to and repel other magnets.
What happens to the force between magnetic poles when their pole strength and the distance between?
Force decreases to half the previous value. Force increases to four times the previous value.
What happens to the force between two unlike magnetic poles?
When two magnets are brought together, the opposite poles will attract one another, but the like poles will repel one another. This is similar to electric charges. Like charges repel, and unlike charges attract. Since a free hanging magnet will always face north, magnets have long been used for finding direction.
What is the force between like poles of two magnets?
The force between two magnets is called the magnetic force.
Magnets always have two poles, a north pole, and a south pole. Like poles repel each… See full answer below.
