One can be stronger, so it can lift bigger objects other cam be small, so it can lift smaller objects. ]]> 2022-03-08 07:34:41 UTC https://padlet.com/mailtomjvaishnavi/8xmo8e7cgz7rdjca/wish/2083463077 MAGNETIC FIELDS: mailtomjvaishnavi https://padlet.com/mailtomjvaishnavi/8xmo8e7cgz7rdjca/wish/2083463078 If the magnetic fields are strong that means that the magnet sired in the fiels will have stronger magnetic force. The strength of the magnetic fields affects the use of the magnet ]]> 2022-03-08 07:34:41 UTC https://padlet.com/mailtomjvaishnavi/8xmo8e7cgz7rdjca/wish/2083463078 MAGNETIC POLES: mailtomjvaishnavi https://padlet.com/mailtomjvaishnavi/8xmo8e7cgz7rdjca/wish/2083463079 Are the two sides of the magnet the south pole and the north pole. If the two poles were south the magnets will separate. If one side was north and the other was south, then both magnets will interact.]]> 2022-03-08 07:34:41 UTC https://padlet.com/mailtomjvaishnavi/8xmo8e7cgz7rdjca/wish/2083463079 lesson 1.

  • Behaves like any other magnet when there is current in the solenoid
  • Have two poles south and north
  • Exerts a magnetic force and magnetic materials
  • The strength of the magnetic field can be increased by adding more turns of wire to the solenoid

    Electromagnets only have a magnetic field when there is a current in the wire.
    both exerts forces on magnets and magnetic materials

  • Speakers: when the electrical current and magnet attract together they produce sound
  • Galvanometer: when the needle and wire attract to the magnet inside the galvanometer it starts to rotate
