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.
What suitable material would you use for the core of an electromagnet?
Iron - use a bunch of iron nails, wrapped many times with insulated copper wire, if making your own electromagnet.
Can the strength of an electromagnet be changed by changing the voltage of the Power Source?
Yes. That's really the only way you have of changing thestrength of the electromagnet while it's operating.
What is the role of an electromagnet in a doorbell?
The electromagnet pulls a plunger which then hits the bell. The action of being pulled, also breaks the power to the electromagnet, so it returns almost immediately, making the power again. This action repeats for as long as the pull push is pressed, causing the plunger to vibrate and the bell to ring.
What precautions you take while conducting specific gravity test?
be careful holding the thermometer
What precautions should be taken while making purchase of govt stores?
Make sure that they are not stolen?
What object is not needed for making a electromagnet?
Every thing except a conducting wire, battery and a soft iron core is not needed for making an electromagnet
Is making an electromagnet a physical process?
Yes
Does making the core of an electromagnet larger make it weaker?
No, the electromagnet is not made weaker by making the core larger. It can be made weaker by decreasing its current and/or turns of coil.
How do you magnetize sphere?
By making it an electromagnet. Include it in a circuit.
How do you magnetize a sphere?
By making it an electromagnet. Include it in a circuit.
How does an electromagnet make the sounds you hear in headphones?
It needs more than an electromagnet. You have an electromagnet with an iron diaphragm in the magnetic field. When the audio current from the amp flows in the electromagnet, the diaphragm moves at the same frequency, making the sound that you hear.
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.
Why electromagnet is different from a permanent magnet because an electromagnet what?
Mainly in that the electromagnet is NOT permanent. In other words, it can be switched on and off.Another relevant difference is that the electromagnet constantly requires power, at least while it is on.
what precautions should be taken while handling fluorine?
Keep equipment dry.
What is the Most suitable for making an electromagnet. a.copper b.iron c.lead d.tungsten?
Iron
What suitable material would you use for the core of an electromagnet?
Iron - use a bunch of iron nails, wrapped many times with insulated copper wire, if making your own electromagnet.
