when metal is brought near a coil of oscillator , eddy currents start to flow in metal that produce their own magnetic field which opposes the source magnetic field . Hence inductance of coil decreases .

How is magnetizing an object the opposite of demagnetizing a magnet?

Demagnetizing. Place the magnet at the opposite end of the metal from where you magnetized it. Again, the magnet must make as much contact with the metal as possible. Rub the metal with the magnet in the opposite direction that you used to magnetize it.


What is an object that attracts metal?

A magnet is an object that attracts metal due to its magnetic field. When a metal object comes in close proximity to a magnet, it is pulled towards the magnet due to the attractive force between the magnetic poles.


How does A student puts a negatively charged object against a metal cabinet. Describe what happens to the charge on the object when it touches the metal cabinet?

Well the metal would obviously attract a charged particle for its charge less surface. The only possible way would be placing a positively charged object on the other side of the negative charged object such that it could counter effect the coulombian pull on the negative charge due to the metal. To keep the positive charge in place it would need to place it within oppositely charged electronic plates. This needs more amendments but thats another topic. When a charged object touches metal, the end result is usually what is known as a static shock.


Why should you avoid touching metal objects during a thunderstorm?

Because electric currents could shock you. Addition: Lightning is attracted to conductive objects such as metal, especially if the conductive object is connected to the ground where the electricity can discharge or complete its circuit. We are made of 90% water, and water is one of the most conductive elements in the world. In the case of lightning from a thunderstorm, touching the metal or any other conductive and connected object, it can be electrically charged or very hot. You could burn yourself or become part of the electrical current.


Can you deflect metal with magnetism?

Yes, metal can be deflected by magnetism through the use of a magnetic field. When a metal object interacts with a strong magnetic field, it can be pushed or pulled in a certain direction due to the magnetic forces at play.

Why does a compass change direction when a metal is near?

When a metal object is brought near a compass, it can disrupt the Earth's magnetic field around the compass. This disruption causes the compass needle to align itself with the new magnetic field created by the metal object, resulting in a change in direction.


A charged object is brought near a metal ball that is mounted on a rubber sheet. If the metal ball acquired a negative charge after it was grounded momentarily what must be the charge of the object th?

If the metal ball acquired a negative charge after being grounded, the charged object must be positively charged. When grounded, the metal ball gained electrons which caused it to become negatively charged. This would only occur if the charged object had an excess of positive charge to transfer to the metal ball.


How does a gold leaf electroscope show that an object is charged?

When a charged object is brought near the metal disc of a gold leaf electroscope, electrons move between the metal disc and the gold leaf, causing the gold leaf to become charged with the same type of charge as the object. This results in the gold leaf repelling from the metal disc, indicating that the object is charged.


When you rub a magnet with metal what happens to the metal object?

When you rub a magnet with metal, the metal object becomes temporarily magnetized. This happens because the atoms in the metal align with the magnetic field of the magnet. However, once the magnet is removed, the metal object loses its magnetism.

The metal rod becomes negatively charged as well through which process?

The metal rod becomes negatively charged through a process called conduction. When a negatively charged object is brought near the metal rod, electrons on the surface of the rod are repelled, causing them to move to the end of the rod farthest from the negatively charged object. This redistribution of electrons creates a negative charge on the metal rod.


What happens to the resistance of a metal when it is heated?

its resistence considerably decreases


What happens to the electrons in a metal object when it is held near a negatively charged object?

The electrons in the metal object are repelled by the negatively charged object and will move away from it. This redistribution of electrons can create a temporary separation of charges on the surface of the metal object.
