What is meant by Tana position?
if the axial line of the magnet passes through centre of the deflection magnetometer it is called as tana position
How do you strengthen a magnet?
A magnet can be strengthened by aligning it with an oppositely charged magnet. They will attract to each other and the weakened magnet will be strengthened through the interaction.
Can magnet pass through wood?
yes it can
How can the magnetism of a permanent magnet be weakened or removed?
Put it in a coil which has an alternating current in it. The AC current produces a magnetic field in the coil which alternates with the changing voltage. This changes the magnetism of the permanent magnet. Gradually reduce the current in the coil and the permanent magnet will end up unmagnetised.
What is the distance between the centre of the magnet from and its one pole if the distance from one pole to another pole is 58.8 cm?
29.4cm

At the centre of a bar magnet magnetism is?
zero
Where do you use magnet to generate energy?
Magnets are used in generators. A magnet is rotated by something, e.g. a wind turbine, and the magnet turns inside a copper coil which generates electricity. It is the opposite of a motor.
Is it true that the magnetic force becomes stronger towards the centre of the magnet?
No.The part of the magnet where there is the strongest pull or attraction are called the poles of the magnet.
Describe the energy transformation that takes place in a generator?
Mechanical energy to electrical energy. A generator consists of a large magnet placed inside a coil of wire. . When the magnet is rotated (mechanical) it impels the electrons in the wire to move(electrical). Conversely, with suitable electrical engineering, when a magnet is placed inside a wire coil and electricity is passed through the wire, it will make the magnet rotate.
What produces an electric current when a coil of wire is wrapped around an iron core is rotated near a magnet?
an inductor
What has happened if a magnet becomes barely magnetic?
There are things (I can't remember their name) that face in one direction on a magnet. When these face in different directions the magnet gradually loses force
Name two things that a magnet force can pass through?
what are the things pass through magnet fields?
What a moving magnet makes?
makes current flow through a magnet
What is a magnet that is creadted from electric current through a wire?
Electro-Magnet
What happens when a strong electric field is passed through a permanent magnet?
The electrons of the permanent magnet would align the way the electromagnetic field passed through the magnet.
How do you strengthen a magnet?
A magnet can be strengthened by aligning it with an oppositely charged magnet. They will attract to each other and the weakened magnet will be strengthened through the interaction.
