they can either attract or repel each other depending upon their polarity
The phenomenon where two parallel current-carrying wires attract or repel each other was shown by André-Marie Ampère in the early 19th century. This is known as Ampère's force law, and it explains the magnetic interaction between current-carrying conductors.
Electromagnets and permanent magnets both attract or repel other magnets and attract iron and other substances. An electromagnet is a magnet that is only active when it has a current passing through it; permanent magnets are always active.
No it does not ! (: Answer 2 Iron is not necessarily a magnet. But if you put a magnet near it, it will be atrracted to it. But if you've magnetised it and you put the other magnet so that the north pole is next to the south pole, then they will repel each other.
When two current-carrying wires are placed close to each other, they generate magnetic fields around them. These magnetic fields interact with each other, causing the wires to attract each other due to the Lorentz force. The direction of the force depends on the direction of the current flow in the wires.
the south side of one magnet attract to the north side of the other magnet; opposites attract. The molecules get attracted.
because of their magnetic field lines
When one magnet moves, it generates a changing magnetic field around it which induces a current in the other magnet, causing it to move in response to the changing magnetic field. This is due to the magnetic attraction or repulsion between the two magnets based on their alignment.
You can strengthen a magnet by exposing it to a strong magnetic field, either by placing it near another strong magnet or using an electromagnet. You can also induce a current in the magnet by tapping it with a hammer or passing an electric current through it to realign its magnetic domains and increase its strength.
The needle that was stroked by the magnet will become magnetized and attract the other needle. The unmagnetized needle will not be affected, so it will not attract the other needle.
When one end of the unmagnetized needle is in contact with a magnet, the magnetic field from the magnet induces magnetism in the needle. This results in the end of the needle touching the magnet becoming a magnetic pole, and the other end becoming an opposite pole. The opposite poles attract each other, causing the unmagnetized needle to attract another needle when in contact with a magnet.
repel and attract
This is called an electromagnet. When an electric current flows through the coils, it creates a magnetic field in the iron core that can attract or repel other magnets. Electromagnets are widely used in various applications such as motors, generators, and magnetic resonance imaging (MRI) machines.
