Factors that can affect a magnet’s strength include:
Q. What happen when the materials were placed near the magnet?
Answer. Answer: 1) When two magnets are brought near each other, like poles repel; opposite poles attract. 2) When a magnet is brought near a piece of iron, the iron also gets attracted to the magnet, and it acquires the same ability to attract other pieces of iron.

Q. What kind of materials were attracted to the magnet?
Ferromagnetic metals are strongly attracted by a magnetic force. The common ferromagnetic metals include iron, nickel, cobalt, gadolinium, dysprosium and alloys such as steel that also contain specific ferromagnetic metals such as iron or nickel. Ferromagnetic metals are commonly used to make permanent magnets.
- Heat.
- Radiation.
- Strong electrical currents in close proximity to the magnet.
- Other magnets in close proximity to the magnet.
- Neo magnets will corrode in high humidity environments unless they have a protective coating.
Q. Does stacking magnets increase pull force?
The more magnet material you stack up, the less increase in pull force you’ll see. We’re measuring the pull force from a magnet to a flat steel surface. As you increase the height (or stack more magnets), each new bit of magnet material you add is farther away from the steel you’re trying to attract to.
Q. How can a magnet attract or repel another magnet even when they are not touching?
Magnets are surrounded by an invisible magnetic field that is made by the movement of electrons, the subatomic particles that circle the nucleus of an atom. Magnets attract when a north pole is introduced to a south pole. If like poles are introduced, either north to north or south to south, the magnets repel.
Q. Which magnet is more powerful natural or artificial?
Artificial magnets are made by man by using different techniques. Natural magnets are found in nature. They are stronger as compared to natural magnets. They are weaker as compared to artificial magnets.
Q. How can we convert an iron strip into a permanent magnet?
Question 7 An iron strip can be converted into a magnet by the following method: Place the iron strip on a table. Place one pole of a bar magnet near one end of the iron strip. Move the bar magnet along the length of the iron strip starting from one end to the other end as shown in the following figure.
