Like polarities repel; unlike attract. So the north ends of two magnets repel each other, as do two south ends, while a north end and a south end mutually attract.

North + North = Repell

South + South = Repell

North + South = Attract

South + North = Attract

What is the law states that 'like charges repel and unlike charges attract'?

This statement is part of Coulomb's Law, which quantifies the electrostatic force between two charged objects. It states that two positively charged objects will repel each other, as well as two negatively charged objects. Positively and negatively charged objects will attract each other.


What makes the needle in a compass move?

When the needle of a compass points in a certain direction that means that the poles of earth have alined it so the point is pointing to the north pole (because earth is a magnet) so In conclusion the poles of earth are being attracted to the opposite pole of the needle because opposites attract and the needles in compasses are designed to point the "pointy" part at the north pole. (pretty smart for an 11year old). To be a little more technical, all magnets have a magnetic field going out from its North Pole and entering back in at its South Pole. When in another magnetic field, the fields will exert a force to try to align the field lines. If near a ferromagnetic material, such as iron, the field lines are distorted and exert a force between the magnet and the metal to realign the fields. Since the compass needle has a small mass, and easily spins, it is usually the object which will move.


What part of a magnet is greatest?

The poles of a magnet are the parts where its magnetic field is strongest. The north and south poles are the regions where the magnetic force is concentrated and where other magnetic materials are most affected.


Why won't a magnet attract a pencil?

Because the only metallic part of a pencil is the extremely thin part at the end that holds the eraser in. It does have enough mass to be attracted by a magnet. Furthermore, pencils don't really has "lead", per se; it is really graphite, a carbon-based compound that is not metallic.


What happens when you break a magnet in half?

Breaking a magnet in half does not result in two separate magnets. Instead, each piece becomes its own magnet with a north and south pole. The strength of the magnetic field in each piece may diminish depending on the quality and material of the original magnet.

What Three properties of a magnet?

1. Magnets attract iron and other ferromagnetic materials such as neodymium and cobalt. 2. Magnets attract or repel other magnets. 3. In addition one part of a magnet will always point north when allowed to swing freely.


What method would you use to test what part of a bar magnet is strongest?

each side has the same strength, but one is north and one is south. North and south attract each other, but north and north or south and south will not attract. Hope this helped!


How do magnets attract and repel each other?

Not only magnets, but metal repel. There are two kinds of charges that metal contain, positive and negative. If you push a positively-charged magnet towards another positively-charged magnet, they'll repel, maybe because one type of charge needs the other to attract. If this one type of charge comes close to another charge of the same kind, it won't receive what it needs, and feel "resent" to the other charge, then repel. If you push a negatively-charged magnet towards another negatively-charged magnet, they will also repel.


What might happen to a metal pair of scissors if rubbed in one direction with the north pole of a magnet?

The metal scissors could become weakly magnetized in the same direction as the north pole of the magnet due to being aligned with its magnetic field. This could cause the scissors to attract or repel other magnetic objects depending on their orientation.


Why would a magnet hung on a string point north?

Actually, they point at the magnetic north and south poles. The Magnetic North Pole is currently somewhere north-east of Canada. The naming of the poles on a magnet is confusing. The north pole would actually be better called the north seeking pole. Answer. Because the Earth itself acts like a massive magnet with its south pole at the Magnetic North Pole and vice versa. Remember 'like poles repel, unlike poles attract'.


A magnet attracts a piece of iron and the iron can then attract another piece of iron .What is the basis of this attraction?

When an iron piece is quite away from the magnet ,i.e, not present in magnetic field of the magnet then the iron piece is in neutral state ,i.e, there is no north & south pole . But , as soon as the iron piece interacts with magnetic field of magnet ,i.e, near to the magnet then the north pole of magnet make the nearer part or end of the iron piece south pole & simultaneously other part of iron becomes north pole . Similarly if south pole of the magnet interacts with iron piece then that end/part becomes north pole & other end becomes north pole . Now this iron piece has north & south pole .So iron piece is now converted into magnet which can attract other iron pieces in similar way as explained before .


Does red attract or repel sunlight?

Red does not attract or repel sunlight. Sunlight is composed of different colors, including red, and all colors of sunlight are absorbed by different objects to varying degrees depending on their surface properties, rather than being attracted or repelled by the color itself.


If you cut off the north pole of a magnet what happens to the remaining part?

it becomes a magnet in it s own right with north and south poles


What is a simple reason to how motors work?

If you take two magnets, you will notice that one end attracts one end of the other magnet and repels the other end. The opposite happens if you flip the other magnet over. It is possible to make an electromagnet by winding wire around a piece of metal. If you attach the wire to a battery it will attract one end of the magnet. If you attach the wire to the other end of the battery, it will attract the other end of the magnet.Also, with electricity, you can use a switch to change which end of the battery will go through which end of the wire. When the magnet comes close to the electromagnet, the motor throws a switch and suddenly the electromagnet repels the magnet. Part of the switch can be attached to the magnet. So motors work because electromagnets can both attract and repel.


What part of the magnet would be the best area to attract metal to?

The strongest magnetic area of a bar magnet is the sides.


What causes magnets to attract the refridgereator?

The force is called "magnetism". The refrigerator is not magnetic, but the magnet will temporarily induce magnetism in the refrigerator's metal - the part that is close to the magnet.


What are 3 properties of magnets?

1. Magnets Attract or Repel Depending on the poles facing each other. 2. Its magnestism or magnetic field decrease if it is broken in half. 3. Magnetic Field is stronger near the poles than in the centres.
