Why will the magnetic field strength be further increased inside a current carrying coil if a piece of iron is also in the coil?
Red apple Orange an orange Yellow school bus Green grass Blue sky Purple Pink Brown dirt Black White
Red- stop sign, apples, tomatoes, beads, jewelery, hair, fire truck, stop lights, paper, crayons, glitter, bikes, toys, blocks, shoes Orange- basketball, orange, pumpkin, cheese Yellow- sun, banana, lemon, fish, stars Green- grass, apple, celery, lettuce, cucumber (green is a good color because you can do different snacks with it) Purple- toys, clothes, backpack, beads Pink - blankets, flowers, rocks, paint Brown- dirt, Chocolate chairs, tables,furniture Black- sunglasses,night, phones, cords White-clouds, ice cream, cotton balls, foam, many things can be used for all the colors for example crayons, paint, blocks, glitter, clothing as well as paper don't forget balloons. you can also create things like shapes and cut them in different colors. play this game daily and it will cause so much fun and it is easy to play. just ask the kids what colors they are wearing. example if the color of the day is green ask who is wearing green today and so on.
You are putting in a piece of magnetic material in the coil and it's magnetic domains will alight with the field increasing the strength.
An electromagnet is an object that acts like a magnet, but its magnetic force is created and controlled by electricity--thus the name electromagnet. By wrapping insulated wire around a piece of iron and then running electrical current through the wire, the iron becomes magnetized. This happens because a magnetic field is created around a wire when it has electrical current running through it. Creating a coil of wire concentrates the field. Wrapping the wire around an iron core greatly increases the strength of the magnetic field. Dr. H
Because the dipoles in a ferromagnetic material (like iron) tend to line up with an applied magnetic field so that they enhance the field from the wires.
