True or False The strength of the magnetic poles in an electromagnet decreases with an increase in the number of turns of wire and the current flowing through them.?
F=N*I so directly proportional
On what factors does the strength of an electroment depends?
The strength of electromagnet depends on the electric current flowing through the core because when the current is stopped, the core is no longer magnetized and the rate of change of flux linkage.
Why does resistance increase in a series circuit?
Depends - in the real world as a resistor gets hotter (current flowing through it) its resistance increases.
Why does energy increase when voltage increases?
If we increase the voltage by adding extra cells or batteries we give the electrical charges more energy and so, the current flowing around the circuit increases.
The difference between charge and current?
Charge is potential, current is flowing.
Two ways to increase the strength of an electromagnet?
-- Increase the current (amperes) flowing through the coil of wire that surrounds the electromagnet. -- Increase the number of 'turns' of wire in the coil.
When and magnetic fields exist its called an electromagnetic field?
A temporary magnetic field created by a flowing electrical current is an electromagnetic field. Stop the current from flowing, it goes away.
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. . .
True or False The strength of the magnetic poles in an electromagnet decreases with an increase in the number of turns of wire and the current flowing through them.?
F=N*I so directly proportional
Would increase the strength of an electromagnet?
More coils of wire around the magnetic material.More current through the wire in the coil.Increasing the current flowing through the wire Increasing the number of loops of wireputting a piece of iron inside the loops of wire apex :)Increasing the current flowing through the wireIncreasing the number of loops of wire
When electric current is flowing in a circuit if the voltage applied to the circuit is increased the?
Correct Answer= "the current will increase"
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 occurs because alternating electrical current flowing through a wire creates an electromagnetic field around the wire?
shorts
On what factors does the strength of an electroment depends?
The strength of electromagnet depends on the electric current flowing through the core because when the current is stopped, the core is no longer magnetized and the rate of change of flux linkage.
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.
If You wrap a wire around a piece of iron. If you slowly increase the strength of an electric current flowing through the wire you would expect .?
The temperature of the wire will increase and eventually like the "straw breaking the camel's back" the wire will fail if you apply enough current. It is like exceeding the current in a fuse, the wire essentially disintegrates.
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.
