What is produced around a wire that has a current?
Magnetic field.
How does electromagnetic induction produce induced current?
Before you can understand how electrical energy is supplied by your electric company, you need to know how it is produced. A magnet and a conductor, such as a wire, can be used to induce a current in the conductor. The key is motion. An electric current is induced in a conductor when the conductor moves through a magnetic field. Generating an electric current from the motion of a conductor through a magnetic field is called electromagnetic induction. Current that is generated in this way is called induced current. To induce a current in a conductor, either the conductor can move through the magnetic field or the magnet itself can move.
How are electromagnetic fields different from a magnetic field?
Electromagnetic fields can be varying in intensity. A magnet is static.
Region around a magnet in which magnetic force can act?
Magnetic freild
Is there a magnetic field around current carrying conductors?
yes.magnetic field present around the conductor.current and magnetic fields are inter related..with current we can produce magnetic field and vice versa
How does an electric current make a magnet?
the electric current is generated by the electric field. thus by the left hand rule when current is passed through a conductor a magnetic field is generated around it so that it is a similar act of a magnet. thus it seems to be a magnet.
Would applying current through a coil which has a permanent magnet at its center increase the magnetic field from the magnet?
no. applying an electrical current to a coil wrapped around a magnet would create a force, which would move the magnet one way or another. to fully understand how to position coils and magnets to get the result you want, google the 'right hand thumb rule'
If you circulated copper wire to magnet and pass current through copper wire it then power of magnet is incrase?
When you pass an electric current through a copper wire that is wound around a magnet, it creates a magnetic field that aligns with the magnetic field of the magnet. This process strengthens the overall magnetic field around the magnet, effectively increasing its power. This principle is the basis of how electromagnets work.
What is the A magnet that has coils of ccurrent-carrying wire around an iron core?
The current produces the magnetic field; such a magnet is called an electromagnet.
How can a magnet induce current in a wire?
When a magnet moves near a wire, it creates a changing magnetic field around the wire. This changing magnetic field induces an electric current to flow in the wire through electromagnetic induction. The current is only induced while there is a relative motion between the magnet and the wire, or if the magnetic field intensity changes.
Where is the field around a magnet strongest?
Where is the magnetic field around a magnet strongest? Answer: A magnetic field is strongest around the poles. Your welcome! :)
Is electromagnet a permanent magnet?
No, an electromagnet is not a permanent magnet. It is a magnet that produces a magnetic field when an electric current is passed through it, and the magnetic field disappears when the current is turned off.
Are the lines that map out the magnetic field around a magnet?
The lines that map out the magnetic field around a magnet are called magnetic field lines. These lines indicate the direction of the magnetic field and its strength at different points around the magnet. Magnetic field lines are closest together where the magnetic field is strongest and they form closed loops that do not intersect.
How can you control the magnetic field of a magnet to turn it on and off?
To control the magnetic field of a magnet and turn it on and off, you can use an electromagnet. By passing an electric current through a coil of wire wrapped around a magnetic material, such as iron, you can create a magnetic field. When the current is turned off, the magnetic field disappears, effectively turning the magnet off.
How is an electromagnet different from a regular bar magnet?
An magnet is a material or object that creates a magnetic field. Bar magnets constantly create their magnetic field, while electromagnets are coils that only produce a magnetic field when an electric current passes through it.
What are the three characteristics of a magnet field by a current?
.
What is the field around a magnet?
A magnetic field. where attraction and repulsion takes place around the magnet.
