Magnetism Story
Texte du Storyboard
- Hey miya, it's me bryan. I have this physics test coming up about magnets and i want you to test me a few questions. So i can make sure that i understand all the materials well
- Sure! Why not. I am really good at physics
- First Question: What are the properties of magnets? And explain them!
- Attractive Property – The Magnet that attracts ferromagnetic materials like iron, cobalt, and nickel.Repulsive Properties – magnetic poles that repel each other Directive Property – A freely suspended magnet always points in a north-south direction
- Well done! 2nd Question: How to map magnetic fields
- placing the plotting compass in adjacent positions in the field it is possible to map out some magnetic lines of force. Using a plotting compass allows the direction of the field to be identified, with the needle of the compass pointing along the field lines from north to south.
- 3rd Question: What are neutral points in magnets?
- neutral point of Magnet is a point at which the resultant magnetic field is zero.the neutral point is obtained when a horizontal component of the earth's field is balanced by the produced by the magnet.
- 4th Question: What does it mean by soft and hard magnetic materials?
- Among the magnetic materials, permanent magnetic materials are also called "hard magnetic materials", which are materials that can maintain constant magnetic properties once they are magnetized.
- Last quetion: Do u know how a magnetic field work?
- Ok i think you are ready for the test. Good luck!
- Yes ofc, a magnetic field is the region around a magnet where a magnetic force is exerted and is represented by lines of force whose direction at any point is the direction of the force on a N pole.
- Thx! Hopefully I can do it well
