no
Drive motor and speakers may have magnets. The tape head that reads (and sometimes records) to the tape may have an electromagnet.
No
Lead is used in magnets.
No, thet don't
Lead is not typically used in magnets. Magnets are usually made from materials such as iron, nickel, and cobalt. Lead is not a magnetic material and is not commonly used in the production of magnets.
A cassette tape is based totally off of a magnetic system. The magnet is what reads and writes the information to the tape.
Magnets can work through materials like plastic, glass, and wood. However, they are less effective through materials like aluminum, copper, and lead. They work best through materials like iron, nickel, and cobalt.
Aluminum is not typically used in magnets. Lead is also not commonly used in permanent magnets due to its low magnetic properties. Instead, materials like iron, nickel, and cobalt are more frequently used in magnets.
Lead tape is basically weighted tape. It can be stuck to things to add weight but keep the object compact.
Some of them do like in the older days but now they don't.
Magnets often contain iron, as it has magnetic properties that align with the magnetic field. Aluminum is not typically used in magnets because it is not inherently magnetic.
Because you know how magnets work.
