Why and how are objects like steel, iron, cobalt, nickel, attracted to a magnet?
nicely you look at it from any opposite direction round and picture of factors that magnets will keep on with. Ovens, fridges, automobile doors, metallic construction doors the helps for street signs and indicators besides because the signs and indicators themselves.
This is because these are metals. When metals are near an electric force the positive charge pushes all the protons away from that side of the substance and therefore only electrons left which are negative. Opposites attract so the two metals come together.
They are magnetic materials NOT MAGNETS. This means that they will be attracted to both sides of the magnet.
