What happens to an electromagnet when there is no current flowing through it?
When there is no current in the wire, their is no magnetic induction. The electromagnet then is simply a coil with no magnetic field associated with it. The moment we allow a current to flow through, there is a magnetic induction and thus we get an electromagnet.
Can a magnetic field exist without electricity?
No, it is not possible for a magnetic field to exist without an electric field.
How does current affect the magnetic field of an electromagnet?
Battery Current Changing the amount of current flowing through the electromagnet will also change the field the it produces. The greater the current in the coil, the stronger the magnetic field will grow. Conversely, lowering the battery voltage decreases the current, weakening the field.
Can the magnetic field around an electromagnet be turned off?
An electromagnet is a coil of wire with an electric current flowing through it. A copper coil carrying a current has a magnetic field like a bar magnet, but it can be switched on and off and reversed. …
What happens to the direction of the magnetic field if the current is reversed?
Answer: The magnetic field generated is always perpendicular to the direction of the current and parallel to the solonoid. Hence if we reverse the current the direction of magnetism also reverses. In other words the magnetic poles gets reversed (North pole becomes south pole and the south pole becomes the north pole).
What happens to the magnetic field when you reverse the flow of current in an electromagnet?
Also as the current is reversed the direction of the magnetic field produced around the conductor will also be reversed because as we have said previously, the direction of the magnetic field depends upon the direction of current flow.
Why was the mystery spoiled?
Why was all the ‘mystery’ spoilt? Solution: The poet Could hear the chatter of the fan, though she could not understand it. But Soon, the Scope to decode and comprehend it was lost as the fan’s motor was oiled by Someone.
