How are electro magnet different from permanent magnet?
Electro magnets differs from permanent magnet because it requires electricity. A simple electro magnet consists of an iron rod wrapped in a coil of copper and when electricity flows through the copper, a magnetic field is formed.
Are seashells magnetic?
no because they are not magnetic and their not made of magnet
How are the uses of an electromagnet different from those of a permanent bar magnet?
A bar magnet is made from magnet materials and has a magnetic field at all times. An electromagnetic is not naturally magnet and only has a magnetic field when electricity is passed through it.
Does salt water passing through a magnet create electricity?
no salt is non magnetic
Can plastic ruler made into magnet?
no it can not .it is because a magnetic meterial can made in to magnet
Can you create electricy from a magnet?
The standard way of generating electricity is moving a wire coil through a magnetic field. So yes
Why is an electromagnet not a permanet magnet?
because the copper wire in it is only magnetic when there is electricity running through it so when you turn of the electricity soure it is no longer magnetic
How do you make a magnetic motor?
Magnet->Electricity->Motor
When a magnet that has a magnetic field only when there is electricity is called?
An Electromagnet
How are electro magnet different from permanent magnet?
Electro magnets differs from permanent magnet because it requires electricity. A simple electro magnet consists of an iron rod wrapped in a coil of copper and when electricity flows through the copper, a magnetic field is formed.
Why does a paper clip stick to a nail when it's on a magnet?
The nail contains iron, which is ferromagnetic. Ferromagnets respond to a magnetic field (from a magnet) by generating their own magnetic field, ie, they become a magnet in the presence of a magnet. They also exhibit hysteresis, in that if they are exposed to a strong enough magnetic field, it will lock in and become a permanent magnet.
What is difference between magnetic circuit and electric circuit?
magnetic circit has a magnet and electri circuit has electricity
Are seashells magnetic?
no because they are not magnetic and their not made of magnet
The process of generating an electric current from the motion of a conductor in a magnet field is?
The process of generating an electric current from the motion of a conductor in a magnetic field is known as induction.
How are the uses of an electromagnet different from those of a permanent bar magnet?
A bar magnet is made from magnet materials and has a magnetic field at all times. An electromagnetic is not naturally magnet and only has a magnetic field when electricity is passed through it.
Why is a magnet useful in generating electricity?
As Faraday discovered, turning a magnet in a coil of wire generates electricity. This is how even today electricity is created, but we use water to turn the magnets in hydroelectricity and so on. It is useful because it is very efficient and it has a mechanical advantage: the force needed to turn the magnet is lss than the force generated by the magnet turning. So basically, to sum it up, the only way to generate electricity is wih a magnet and a solenoid (coil)
Can a round magnet produce electricity if it's rotating?
The shape of the magnet is unimportant. Any moving magnet can induce a voltage in a wire. Or any changing magnetic field. If the magnet rotates, its magnetic field will change, so yes.
