How do you make a electromagnet stronger?
For a simple copper wire around iron nail electromagnet, increasing the number of rounds the copper wire makes around the nail will increase the electromagnet's strength. Also, increasing the voltage applied(adding a battery) will increase the magnetic field.
What is the similarities between a bar magnet and a electromagnets?
Both are magnets, but an electromagnet needs electricity to become a magnet. Hence, a magnet is also the same as a electromagnet.Also a magnet Will attract ferrous metals as will an electromagnet, when switched on!
Do magnetic field lines always cross?
Actually, they NEVER do.
Electromagnets are created using what?
An electric current flowing in a wire creates a magnetic field around the wire. To concentrate the magnetic field of a wire, in an electromagnet the wire is wound into a coil, with many turns of wire lying side by side. The magnetic field of all the turns of wire passes through the center of the coil, creating a strong magnetic field there. A coil forming the shape of a straight tube (a helix) is called a solenoid; a solenoid that is bent into a donut shape so that the ends meet is called a toroid. Much stronger magnetic fields can be produced if a "core" of ferromagnetic material, such as soft iron, is placed inside the coil. The ferromagnetic core magnifies the magnetic field to thousands of times the strength of the field of the coil alone. This is called a iron-core electromagnet.
When a conductor is moved through a magnetic field the force of the magnetic field generates what in the conductor?
Yes Ofcourse ,when a curren is allowed to pass through a conductor,"IT IS BEING SURROUNDED BY MAGNETIC FIENLD".... Because it somehow behaves as the electromagnet as per FARADAY LAW OF ELECTROMAGNETIC INDUCTION.............
How is a permanentmagnet different from a electromagnet?
a permanent magnet is always magnetic as an electromagnet is only magnetic when it is wound around with wire and energised
What does a electromagnet create?
a magnetic field
What is difference between of Electromagnet and Electric Magnetic Field?
An electromagnet is a magnet that only generates magnetic forces when electricity is running through it, basically a magnet that can be turned on and off. An electromagnetic field is the magnetic force generated when an electromagnet is used.
Can an electromagnet create a magnetic field when the battery is removed?
If the electromagnet has a core, which has become magnetized, then the core will have a residual magnetic field when the power is removed.
What happens when you decrease the current in an electromagnet?
When you decrease the current in an electromagnet, the magnetic field decreases.
Strong temporary magnet formed when a current is passed through a coil of wire?
A magnetic field.
Is Venus electromagnet?
No. Venus has no magnetic field.
What kind of magnet is used in the hotel room door?
Electro Magnetic is correct
How is an electromagnet different from a refrigerator magnet?
A refrigerator magnet is magnetic because it is a "permanent" magnet. An electromagnet is a magnetic field caused by a current flowing through a wire.
Which has a stronger magnetic field a solenoid or a electromagnet?
A solenoid is an electromagnet An electromagnet is a solenoid with an iron core
How are electromagnet and a bar magnet alike?
Both are magnetic.
The magnetic field of an electromagnet is similar to that of a magnet?
bar
