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 .

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.
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.
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.
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.
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.
It decreases
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.
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.
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, 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 closest album to metal that they have is I Brought You My Bullets, You Brought Me Your Love. None of them are really metal though, more punk.
[object Object]
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.
its resistence considerably decreases
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.
In order to know what a metal object is on a dorm wall one would need more information. If a description of the metal object is given one may be able to determine what the object is.
Heating a metal decreases the tensile strength and increases ductility
