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

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

Electric vs Gravitational Force

Similarities Differences
Both have fields Electric force can be both repulsive and attractive but gravity only attracts
Both have potential lines Electric force results from charge but gravitational force results from mass

What is attract repel?

The north pole of one magnet will always attract the south pole of another magnet. If two south poles or two north poles are placed near one another, they will repel each other. When two magnets repel, they push away from one another.

What is the force of attraction of a magnet the maximum?

The attractive property of a magnet is maximum at north and south poles both.

What are the various ways in which magnet can lose their magnetism?

Elevated temperature: Magnetic materials lose magnetism as they heat, but they regain magnetism when cooled provided the maximum temperature is below their Curie temperature. Above the Curie temperature, a magnet permanently loses all or some of its magnetism.

What are soft and hard magnetic materials?

Soft magnetic materials are those materials which have a smaller area enclosed by their Hysteresis loop. Hard magnetic materials are those materials which have a Larger area enclosed by their Hysteresis loop. 2. They have low remnant magnetization. They have high remnant magnetization.

How should magnets be stored?

Store magnets in closed containers so they don’t attract metal debris. If several magnets are being stored, they should be stored in attracting positions. Because they can easily become demagnetized, alnico magnets should be stored with “keepers”, iron or magnetic steel plates that connect the poles of the magnet.

What 4 precautions do you take to protect magnets from losing their property?

Precautions to Protect Magnets from Losing Their Magnetic…

  1. Never drop magnets from heights.
  2. Never heat a magnet.
  3. Do not hammer a magnet.
