What flows through a circuit and causes a magnetic field?
An electric current flowing through a circuit causes a magnetic field. This is due to the movement of electric charges, usually electrons, in the circuit. The magnetic field produced is perpendicular to the direction of the current flow.
What causes electric magnetic wave?
Accelerating electric charges.
What causes an electric current to keep moving?
What causes an electric current to keep moving is a steady supply of electrons.
What causes an electric motors magnetic field to collapse?
the answer is rotational force
What are the two causes of electric and magnetic forces?
mainly positive and negative charges
How do you show that electric current causes magnetism?
Put a wire carrying an electric current near a compass and it causes the needle to deflect.
How electric current causes magnetic field around conductor?
Electric current causes magnetic field around conductor by producing a moving electric charges and the intrinsic magnetic moments of an elementary particles that is associated with a fundamental quantum property.

Do magnetic effect of electric current causes a change in colour in a solution through which electric current is passed?
i don't believe it does
What do you mean by heating and magnetic effect of electric current?
When electric current travels through a conductor, there is always resistance. This resistance causes some of the energy of the current to express as heat. Additionally, the movement of the current causes a magnetic field to form around the current in a clockwise direction. This principle is what allows coil heaters and induction motors to operate.
What causes a electric current in a electric circuit?
Voltage causes current to flow in an electric circuit.
What causes electric magnetic wave?
Accelerating electric charges.
What causes a current in an electric circuit?
Voltage causes current to flow in an electric circuit.
Does electric currents cause coils in magnetic fields to move?
yes, electric feilds do cause the magnetic feilds in the coils, this was first observed by Hans Oersted in 1819. He showed that when an electric current was passed theough a wire a nearby compass needle showed a deflection, this prooves that an electric feild causes an magnetic feild.
How are electric currents and magnetism related?
Magnetism could be produced due to the flow of electrical current. This was first discovered by Oersted. By changing the magnetic flux linked with a coil electric current could be induced. This was first studied by Michael Faraday. Just due to the orbital motion or spin motion of electron magnetism is produced in tiny form and is known as magnetic dipoles. Such dipoles getting oriented in different form lead to form dia, para and ferro magnetic materials.
The magnetic field strength inside a current-carrying coil will be greater if the coil encloses a?
If the coil encloses an iron rod, then the magnetic field strength inside a current-carrying coil will be increased. This occurs because the air path in the coil is made shorter by putting in the rod. This in turn causes an increase in the field.
Can you make a magnet without using a magnetic material Explain?
If you are referring to a magnet as an object that possesses a permanent magnetic field, then yes. There are three circumstances where magnetic fields exist, but not as a result of a permanent magnet. 1. Electric current causes a magnetic field. Thus, any wire carrying a current or even a current without a wire (like a lightning bolt) will be surrounded by a magnetic field. Since electric current is made up of moving electric charges, it is actually true than any moving electric charge creates a magnetic field. 2. It is difficult to observe outside of a scientific laboratory, but when there is an electric field that is varying in time, that creates a magnetic field. Though not easy to demonstrate directly, this turns out the physical phenomena the allows the creation of elecrtromagnetic waves, e.g. like the light we see with our eyes. 3. Thirdly, one can cause materials that are not able to work as permanent magnets to act as temporary magnets. This is the basis for electromagnets. A steel or iron core with an electric current running through a coil surrounding the core will produce a magnetic field. If you simply cut off the power source, the electric current will no longer flow through the coil. No electric current, no magnetic field. When a non-permanent magnet is created, the magnetic field it produces is just the same as the magnetic field of a permanent magnet, until the source is removed and the field disappears. All of these matters together are an essential part of the basics of electromagnetism which describes how and why the phenomena work.
