What happens when you add more coils to the wire in an electromagnet what else can you do to increase the magnetic field of an electromagnet?
The more loops gives the magnet more voltage. More loops produce more currents. The current that is induced as acts like an opposing magnet and makes it more difficult to move the magnet.
What will cause an increase in current flow in a simple series circuit?
Increase current by either increasing the voltage or decreasing the resistance.
How can a electromagnet pick up more metal things?
More than what? - An electromagnet can pick up metal due to its magnetism - assuming it is turned on. If you increase the current, the electromagnet becomes more powerful - but you must be careful not to pass too much current, otherwise the wires might burn through.
How can you increase a current in a wire?
Ohm's law. Current is directly proportional to the applied emf and inversely proportional to the resistance in the circuit.
What is a magnet made by electric current?
An electromagnet.
What happens if you increase the current in an electomagnet?
As current increases, the electromagnet strength will increase.
How can the strength of an electromagnet be increased or decreased?
the current from the battery controls the strength of the electromagnet. Adjusting the voltage will also adjust the current as will adjusting the resistance in accordance with Ohm's Law. Current= voltage/resistance
What happens to the strength of magnetic force in an electromagnet when increasing the current through the coil?
The strength is increased, this is how Roller Coasters operate.
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.
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
How can the magnetic field strength of an electromagnet be reduced?
Either increasing the size of the current (in amps) or the number of turns of wire wrapped around the core will make a stronger magnet. A larger current will make a stronger magnet (up until too much makes the wire melt!). Increasing the voltage forces more current through the electromagnet.
Why does the strength of the electromagnet increase from the coils?
The electromagnet is made stronger in proportion to the current given. Refer to the link provided for more information.AnswerWhen current passes through the coil of wire surrounding the core of an electromagnet, it acts to align the magnetic domains within that core. Once all the domains have been aligned, the electromagnet has reached 'saturation' and is as strong as it can get. So the strength of an electromagnet is NOT proportional to its magnetising current.
How can the strength of an electromagnet be increased?
More currents, or more loops.
What will increasing the electric current to an electromagnet do to its magnetism?
An increasing electric current moving into an electromagnet will become stronger in its magnetism. As the atoms align the increasing magnetism will stop at one point, making the electromagnet as strong as it can be.
How can you increase the strength of a electromagnet?
More currents, or more loops.
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
What happens when you add more coils to the wire in an electromagnet what else can you do to increase the magnetic field of an electromagnet?
The more loops gives the magnet more voltage. More loops produce more currents. The current that is induced as acts like an opposing magnet and makes it more difficult to move the magnet.
