Magnetism is used in the tape drive motor, In the solenoid that moves the tape head to press against the tape. To erase the recording as the tape is moved past.
Devices such as electric motors, generators, and transformers rely on magnetism to function. Magnetic resonance imaging (MRI) machines in healthcare also utilize magnetism to produce detailed images of the body's internal structures. Additionally, speakers and headphones use magnets to convert electrical signals into sound waves.
Direct current (DC) is the unidirectional flow of electric charge."Conductivity" is just the ability of a substance to conduct electric current.Copper and silver have a lot of conductivity. Glass has very little of it.
When we turn of the current in an electromagnet then electromagnet looses its magnetic property,provided the material used inside the current carrying solenoid is soft iron core. If, the material is steel then after the current is turned the magnetism propety still prevails and hence steel becomes a permanent magnet.
Magnetism is a condition of being, not a type of metal, and metals don't typically attract metals. Anything containing iron can become magnetized. All it takes is exposing it to a magnet or applying a DC current to a coil wrapped around it.

Yes, it has electronic components inside that are powered by electricity (either mains AC and or battery DC).
AC motors are not suitable for tape recorders because the speed can not be kept sufficiently constant. Tape recorders use dc shunt-wound motors with electronic speed control.

The following describes a method for using the Power Recorder to monitor and log the ripple voltage on a direct rectified DC power rail. # Set the Recorder to "Split Single Phase" # Connect N & G to the DC rail negative # Connect A to any mains input phase # Connect B to the DC rail positive
what are the advanced applications of dc series motor
due to residual magnetism
Sure you can if the tape player is a 12 volt DC player.
It is a cable that goes into an electric plug on your wall on its one end and into the DVD recorder on the other end, and supplies power / electricity to the recorder device. The cable should be included with the recorder in the same package. If not, I would return the product or request the cable.
applications of series motor
voltage regulator is a component to convert pulsating DC into constant DC.
It is depends on the application. If we need any variable speed in motor, dc motor will be better choice.
both. it depends on the application.
