Where can a magnetic field are produced?As Ampere suggested, a magnetic field is produced whenever an electrical charge is in motion. The spinning and orbiting of the nucleus of an atom produces a magnetic field as does electrical current flowing through a wire. The direction of the spin and orbit determine the direction of the magnetic field.
Can a magnetic field be made?While electric charges can create electric fields, magnetic fields can also create electric fields. Similarly, while magnets can create magnetic fields, electric fields can also create magnetic fields. In fact, every time you change a magnetic field, you create an electric field.
How can you make a magnetic field without electricity?Consider a rod with an equal number of positive and negative charges (such that they are equally spaced). Let the positive move to the left with speed v and the negative to the right with speed v. This will result in a magnetic field but no electric field.
How magnetic field is produced in matter?Magnetic fields are produced by moving electric charges and the intrinsic magnetic moments of elementary particles associated with a fundamental quantum property, their spin.
Where can a magnetic field are produced? – Additional Questions
Can you project a magnetic field?
Physicists in the UK and Spain claim that they have found a way to generate and manipulate magnetic fields at a distance. This opens up the possibility of projecting magnetic fields into inaccessible spaces and enables the remote cancellation of magnetic sources, the researchers say.
How can we make magnetic field at home?
Can you generate a magnetic field remotely?
“If you cannot have a magnetic field maxima in empty space, it means you cannot create the field of a magnetic source remotely, without placing an actual [magnetic] source at the target location,” said Rosa Mach-Batlle, a physicist at the Istituto Italiano Di Tecnologia Center for Biomolecular Nanotechnologies in Italy
How do you create a magnetic field in physics?
You can create magnetic fields by simply finding magnetic materials in the ground and moving them where you want them, or by running electricity through a wire: moving charges create magnetic fields, and electric wires contain moving charges.
What are two ways to create a magnet?
Magnets are made by exposing ferromagnetic metals like iron and nickel to magnetic fields. There are three methods of making magnets: (1) Single touch method (2) Double touch method (3) Using electric current.
Can electricity create magnets?
What are the four methods of making a magnet?
Electrical Method. A steel bar or iron bar is placed inside a solenoid as shown below.
Contact Method or Stroke Method. The contact method is divided into two: single touch and divided touch.
Single touch/Stroke. The iron bar (specimen)is placed on a bench.
The three methods of making magnets are: Using Electric Current. Single Touch Method. Double Touch Method.
How are permanent magnets made?
Permanent magnets are made from “hard” ferromagnetic materials such as alnico and ferrite that are subjected to special processing in a strong magnetic field during manufacture to align their internal microcrystalline structure, making them very hard to demagnetize.
Can you make a permanent magnet with electricity?
It turns out that if you have the right type of metal rod and enough electrical power, electromagnetic induction can turn the rod into a strong permanent magnet.
