What happens to copper and a magnet?
When a magnet is placed near a copper material, no attraction or repulsion occurs because copper is not a magnetic material. However, moving a magnet near a copper wire induces an electric current to flow through the wire, a phenomenon known as electromagnetic induction.
How do you prevent electric shock when working with electrical appliances?
To prevent electric shock when working with electrical appliances, always unplug the appliance before cleaning or servicing it, avoid using appliances near water, and make sure to use insulated tools when working on them. Additionally, ensure that the appliance is properly grounded and never overload electrical outlets.
Why a horse shoe magnet is used in sonometer?
A horseshoe magnet is used in a sonometer to create a magnetic field that can interact with a vibrating metal strip (sonometer wire) to produce sound. When the magnet is placed near the wire and the wire is set into motion, the changing magnetic field induces an electrical current in the wire, which creates vibrations that produce sound waves.
Why is magnetism induced into an iron bar placed near a magnet?
When an iron bar is placed near a magnet, the magnetic field of the magnet aligns the magnetic domains within the iron bar. This alignment increases the overall magnetic field strength of the iron bar, effectively inducing magnetism in the bar.
When is induced electromotive force produced in a coil placed near a magnet?
An induced electromotive force is produced in a coil placed near a magnet when there is a relative motion between the coil and the magnetic field. This motion causes a change in the magnetic flux passing through the coil, leading to the generation of an electromotive force according to Faraday's law of electromagnetic induction.
What might occur if electrical appliances are used near water?
you will DIE
Why should electrical appliances not be used near water?
Because it can kill you.
How does a non magnetic material behave when a magnet is placed near?
A non-magnetic material will not be attracted to a magnet and will not exhibit any magnetic properties. It will not stick to the magnet or experience any noticeable changes in its behavior when the magnet is placed near it.
Is calcite attracted to a magnet?
No, calcite is not attracted to a magnet because it is not a magnetic mineral. Calcite is a non-magnetic mineral and will not exhibit any magnetic properties when placed near a magnet.
What can you conclude if you place the north pole of a bar magnet near the pole of an unmarked magnet and they repel?
That you have placed the magnet towards the northern pole of the unmarked magnet. Like poles retract while opposite poles attract
What happens when a nail is placed near a magnet?
When a nail is placed near a magnet, it can become magnetized due to the magnetic field of the magnet. The magnet induces a magnetic alignment in the nail's iron atoms, causing the nail to exhibit its own magnetic properties. If the magnet is strong enough, the nail may even be attracted to the magnet, demonstrating the principle of magnetism in ferromagnetic materials. Once removed from the magnetic field, the nail may retain some magnetization but will generally lose most of it over time.

What happen to a metal place near magnet?
When a metal object is placed near a magnet, the magnetic field of the magnet exerts a force on the free electrons in the metal, causing those electrons to align in the same direction. This alignment creates a magnetic field in the metal, which either attracts or repels the original magnet, depending on the orientation of the magnetic poles.
Why a horse shoe magnet is used in sonometer?
A horseshoe magnet is used in a sonometer to create a magnetic field that can interact with a vibrating metal strip (sonometer wire) to produce sound. When the magnet is placed near the wire and the wire is set into motion, the changing magnetic field induces an electrical current in the wire, which creates vibrations that produce sound waves.
Where should CO2 detectors be placed in a home for optimal safety?
CO2 detectors should be placed on every level of the home, near sleeping areas, and in areas where carbon monoxide sources are present, such as near gas appliances or a garage.
What happens when two like poles are placed near each other?
they create an electrical current
