Why deflection of the magnetic needle placed in a coil carrying current increases as the number of turns in the coil increases?
Deflection of the magnetic needle placed in a coil carrying current increases as the number of turns in the coil increase because as the number of turns in the coil increases the strength of the magnetic field also increases.
What is the relationship between the stength of an electromagnet and the number of turns in the coil?
As the number of turns in the coil increases, the strength of the electromagnet increases.
Producing an electric current by moving a bar magnet in and out of a coil of wire is called?
Electromagnetic induction.
How do the size of the current in the coil affect the strength of a electromagnet?
It's directly proportional.
Why the the reading on the newton meter increases when a current passes through the coil?
because it becomes more magnetic therfore it the pull on the coil will increase
Why deflection of the magnetic needle placed in a coil carrying current increases as the number of turns in the coil increases?
Deflection of the magnetic needle placed in a coil carrying current increases as the number of turns in the coil increase because as the number of turns in the coil increases the strength of the magnetic field also increases.
What is the highest and lowest voltage of an electromagnet?
The strength of an electromagnetic is determined completely by the current through its coil, and doesn't depend on the voltage across the coil. The voltage will be (current) x (resistance of the coil).
What will happen when the number of turns of wire and the current flowing them increases?
The strength of the magnetic field inside the coil increases.
What is current coil and voltage coil?
The current coil is one through which the current of source can pass. This coil is connected in series. The voltage coil is connected parallel to the applied voltage. In the current coil the quantity of current flowing is proportional to the current flowing in load while in the voltage coil, current flowing is proportional to applied supply voltage. The voltage coil current is independent of current flow in load. For a complete understanding, please refer to a watt meter diagram.
What is the relationship between the stength of an electromagnet and the number of turns in the coil?
As the number of turns in the coil increases, the strength of the electromagnet increases.
What happens to the strength of your electromagnet if you use more turns of wire?
Answer you can increase the strength of an electromagnet by: 1) Increasing the current flow 2) Increasing the number of coils 3) Passing an 'iron core' through the coil of the electromagnet
For a current carrying coil if the current is doubled then the field strength is?
doubled
How is electromagnetic induction defined?
When there is relative motion between a magnet and a coil of wire, an electric current starts flowing in the coil. This phenomenon is called electromagnetic induction.When lines of a magnetic field cross the line of an conductor, electric current is induced in it.
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.
Producing an electric current by moving a bar magnet in and out of a coil of wire is called?
Electromagnetic induction.
What controls the strength of a magnet made with electric current?
The strength of a magnet(electromagnet) made by flowing electric current through a conducting coil depends on magnitude of current. . .
Can tesla coils generate an emp?
the coil it is used to produce high voltage, low current, high frequency alternating current electricity. A burst of electromagnetic radiation is something the coil will not do.
