Detailed explanation-1: -Earth’s magnetic poles are not in the same place as the geographic poles. Magnets cannot interact without touching. Magnetic field lines always cross. The effects of a magnetic field can be observed using non-metal filings.
Detailed explanation-2: -true or false the effects of a magnetic feild can be observed using non-metal filling. AI Recommended Answer: True.
Detailed explanation-3: -Iron filings are small shavings of a ferromagnetic material. Ferromagnetic (for the purposes of this page, at least) means that they will align themselves with a magnetic field. That being the case, iron filings are an excellent way to display the magnetic field of one or multiple bar magnets.
Detailed explanation-4: -In fact, every material – wood, plastic, even water – will respond to a magnetic field, if it’s strong enough. That’s because every material possesses a property known as diamagnetism, by which the electrons within the material repel magnetic fields.
Detailed explanation-5: -The materials that will redirect magnetic fields are materials that are ferromagnetic (attracted to magnets), such as iron, steel (which contains iron), cobalt, and nickel. Iron: Iron is a ferromagnetic material, which means it is strongly attracted to magnets and can be used to block a magnetic field.
