2. Magnetic domains create magnetic fields.
3. Spins are usually written in opposite sides in order to cancel each other. 
4. When substances have unpaired electrons, that leads to ferromagnetism. ]]> 2023-02-06 06:52:39 UTC https://padlet.com/icedulb/nulorkmdimc0uzbz/wish/2469598418 Michael and Gaia https://padlet.com/icedulb/nulorkmdimc0uzbz/wish/2469602509 1 ) The force generated by the aligned atoms creates a magnetic field.
2 )  northern light occure when charged particles (electrons and protons) collide with gases in Earth's upper atmosphere. 
3 )the solar wind would strip our atmosphere, and the oceans would evaporate and be lost to space. In other words, Earth would end up like Mars.
4 ) the magnet will point nord .]]> 2023-02-06 06:56:08 UTC https://padlet.com/icedulb/nulorkmdimc0uzbz/wish/2469602509 Kai - Yohan - Marc Yamin kaboukaram261 https://padlet.com/icedulb/nulorkmdimc0uzbz/wish/2469606973 - Magnetic fields work just like electric fields. The field lines appear to begin at the north pole of the magnet and end at the south pole, but they do not have a starting and ending point, they are all loops. 
- This question is irrelevant. 
- If the magnetic fields does not exist in the earth, the solar wind could render life on earth impossible. 
- The magnet points towards the north.  ]]> 2023-02-06 06:59:34 UTC https://padlet.com/icedulb/nulorkmdimc0uzbz/wish/2469606973 Ralph Raphael https://padlet.com/icedulb/nulorkmdimc0uzbz/wish/2469607496 1)Magnets are used to make a tight seal on the doors to refrigerators and freezers

2)when a bar magnet is cut into half both the halves will have a north pole and a south pole each

3)A magnetic field can be produced by either a current, a flow of charged particles or a magnetised material. The pole of a magnet, a current-carrying wire or a moving charged particle in a magnetic field will feel a magnetic force.

4)When two magnets are brought together, the opposite poles will attract one another, but the like poleswill repel one another. This is similar to electric charges. Like charges repel, and unlike charges attract.

5)It has two poles, a north and a south pole such that when suspended freely, the magnet aligns itself so that the northern pole points towards the magnetic north pole of the earth.

6)he magnetic field protects our planet from cosmic radiation and from the charged particles emitted by our Sun

7)A magnetometer is a device that measures magnetic field or magnetic dipole moment. Different types of magnetometers measure the direction, strength, or relative change of a magnetic field at a particular location.]]> 2023-02-06 07:00:10 UTC https://padlet.com/icedulb/nulorkmdimc0uzbz/wish/2469607496 ray rdoumit26_2 https://padlet.com/icedulb/nulorkmdimc0uzbz/wish/2469608083 1: false they do form loops

2. the magnetic field protects life on earth . without the magnetic field the solar wind could render life on earth impossible
3.  earphones and television 
4. because its where the earths south magnetic pole is located. North and south attract  ]]> 2023-02-06 07:00:36 UTC https://padlet.com/icedulb/nulorkmdimc0uzbz/wish/2469608163 Gaia-micheal https://padlet.com/icedulb/nulorkmdimc0uzbz/wish/2469610936 1) when you cut a magnet in half, it forms north and south poles on each half and they become 2 separate magnets.
2) the magnetic field protects the earth from the charged particles coming from the sun.
3) magnets on the fridge, or a compass.
4) the north pole of the compass attracts to the south pole of the earth’s “magnet” and vice versa, which means the “north’ indication of the magnet is attracted to the north pole]]> 2023-02-06 07:02:35 UTC https://padlet.com/icedulb/nulorkmdimc0uzbz/wish/2469610936 andy https://padlet.com/icedulb/nulorkmdimc0uzbz/wish/2469611301 1.When a bar magnet is cut into half both the halves will have a north pole and a south pole each.
2.The magnetic field protects our planet from cosmic radiation and from the charged particles emitted by our Sun. It also provides the basis for navigation with a compass.
3.
  • Magnets are used in magnetic compass, doorbells, refrigerators.
  • Magnets are used in dynamos, motors, loudspeakers, microphones etc.
  • Ceramic magnets are used in computers.
  • Magnets are used in toys to give a magic effect.
4.. Earth's magnetic north pole is near Earth's geographic south. That's why the north pole of a compass points toward north because that's where Earth's south magnetic pole is located and they attract.
