How do you change the direction of a magnetic field?
You can change the direction of a magnetic field by reversing the flow of electric current in a wire or by changing the orientation of a permanent magnet. Alternating the direction of current in a coil can also reverse the direction of the magnetic field it produces.
What is magnetic field produced by a current flowing through a wire?
A current flowing through a wire produces a magnetic field around the wire. The direction of the magnetic field is determined by the right-hand rule, where if you point your thumb in the direction of the current, your fingers will curl in the direction of the magnetic field lines. The strength of the magnetic field is directly proportional to the current flowing through the wire.
A current in a long straight wire produces a magnetic field. These magnetic field lines?
form concentric circles around the wire, with the direction given by the right-hand rule (curl your fingers in the direction of the current, and your thumb points in the direction of the magnetic field). The strength of the magnetic field decreases as you move further away from the wire.
Definition of a magnet?
A magnet is an object that produces a magnetic field, which can attract or repel other materials that are capable of being magnetized. Magnets have two poles – a north pole and a south pole – which exhibit different magnetic properties.
What is the relationship between a magentic force and a magnetic field?
A magnetic force is the exertion of a force on a magnetic object due to the presence of a magnetic field. The strength and direction of the magnetic force depend on the strength and orientation of the magnetic field. In essence, a magnetic field produces the magnetic force that acts on magnetic objects within its influence.
Are domains alligned in magnets?
Yes. When a material is magnetized the magnetic domains are aligned.
What is the difference between a magnet and magnetic material?
magnet attracks magnegtic material but magnetic meaterial does not atterck or repel\ magnet attracks magnegtic material but magnetic meaterial does not atterck or repel\The magnetic material is any material in which for a short time the domains are alligned in same direction.This material can be anything like iron,etc.The magnet is a steel in which the domains are permanently arranged in same direction by rubbing method.
How do you change the direction of a magnetic field?

An electric current produces?
Produces magnetic fields, that are used in generators, inductors and motors. The magnetic field at any given point is specified by both a magnitude and a direction.
Coil made up of which material produces highest magnetic flux?
I think cooper coil

What is definition of paramagnetic and dimagnetic materials?
A dimagnetic material produces a magnetic field that opposes an external field. A paramagnetic materia, on the other hand, produces a magnetic field that increases an external field. Dimagnetism and paramagnetism are induced when an object is placed in a magnetic field.
Does an electric current produces a magnetic field?
yes*edit: don't confuse moving with changing. A change in magnetic field strength/direction will induce an electric current.
A current in a long straight wire produces a magnetic field. These magnetic field lines?

What are the physics behind dropping a magnet down a metal pipe?
As a magnetic field passes by a ferrous material an electric current is created locally in that material, in this case the pipe. Anytime an electric current is produced that changes with time, a magnetic field is generated. The magnetic field that the pipe produces creates a force in the opposite direction of gravity. This magnetic field created by the pipe affects the magnet falling and creates a breaking force. This whole thing is refereed to as Eddy Currents.
