What device is most likely to contain an electromagnet?
A speaker is most likely to contain an electromagnet to produce sound by vibrating a diaphragm.
Does a flashlight contain an electromagnet?
No, a flashlight does not contain an electromagnet. Flashlights typically use batteries to power a light bulb or LED for illumination.
What does not contain in a electromagnet?
An electromagnet does not contain permanent magnets. It consists of a coil of wire wrapped around a ferromagnetic core, such as iron, that becomes magnetized when an electric current flows through the coil.
Does a flashlight contain an electromagnet?
No. Except for the kind that you wind up to power.
What kind of things attach to a electromagnet?
Objects that contain ferromagnetic materials such as iron, nickel, or cobalt are attracted to an electromagnet. For example, paperclips, nails, and small metal objects will stick to the electromagnet when it is energized.
How do darlington transistors work?
A Darlington transistor it may contain one or more transistor in its case. the purpose is to amplify current by beta multiplication.
What are some objects that contain an electromagnet?
Some objects that contain an electromagnet include electric motors, speakers, MRI machines, and doorbells. Electromagnets are also used in cranes, magnetic levitation trains, and particle accelerators.
What does a electromagnet create?
An electromagnet creates a magnetic field when an electric current passes through a coil of wire, which magnetizes the core of the electromagnet. This magnetic field allows the electromagnet to attract or repel other objects that contain iron, nickel, or cobalt.
How many pn junction does transistor contain?
Two, either in NPN or PNP transistors
What will attract to a electromagnet?
An electromagnet will attract materials that contain iron, nickel, or cobalt. These materials are ferromagnetic, which means they are strongly influenced by magnetic fields and will be pulled towards the magnet when in close proximity.
How do i know that they have electromagnet in the motor?
because it will contain a magnet inside that spins with copper windings like a car alternator
What is the purpose of transister?
The correct spelling is transistor. The definition of transistor is a portable radio that uses circuits that contain transistors instead of vacuum tubes. It is a semiconductor device that has three connections.
