Method We wrapped a wire around an iron nail and connected it to a D.C power supply. Professor Oersted is a physics professor who discovered that a wire carrying electric current generated a magnetic field. The hypothesis is basically a prediction of what is going to happen in an experiment before the experiment is done. Implementation of any Science Project Idea should be undertaken only in appropriate settings and with appropriate parental or other supervision. An electromagnet is just like a regular magnet except that it is powered from electric currents. I just wanted to say thank you very much for the Science lessons yesterday. He referred to this phenomenon as electromagnetism.

Hypothesis I think that increasing the number of turns on a coil will increase the strength of the electromagnet.

My son eagerly announced that he wanted to join, so I filled … For scientists, disproving a hypothesis still means they gained important information, and they can use that information to make their next hypothesis even better. Professor Hans Christian Oersted coined the term electromagnetism in 1820, which refers to the ability of a wire to carry electric current to produce a magnetic field. Stem Science Easy Science Science Experiments Kids Science Education Science Lessons Teaching Science Science For Kids Science Activities Science And Technology How to Make a Simple Motor This is a great project for use in the classroom or at home. In this science project, you will be creating your own electric generator. The hypothesis is basically a prediction of what is going to happen in an experiment before the experiment is done. Creating an electromagnetic crane is a simple science fair project that demonstrates one of the most important principles in electromagnetism. This principle comes in very handy in the form of an electromagnet.

An electromagnet is the same way, except it is "temporary" -- the magnetic field only exists when electric current is flowing.

Then she uses that information to form a tentative answer to her scientific question. A good hypothesis is one that is plausible, testable, and refutable. Experiment Results - The Strength Of An Electromagnet ... Hypothesis – I think this will happen because if there is a large amount of coils not much magnetism will get through whereas is thee is less, more will get through.

A few days ago, a flyer came home in my son's homework folder announcing the start of a Robotics Club at his school.
You can also buy displays at many retail stores that work well with your magnet project. If you turned the electromagnet you made into a science fair project, name three variables you would have to control and how you would control them.
An electromagnet operates only when there is a flow of electricity in the coil of the wire. The magnetic field is created when the wire is tightly coiled around an object, this gives off a strong magnetic field. An electromagnet is a type of magnet that attracts metals with the help of electricity. However you do it, make sure you follow science fair rules! An electromagnet is a type of magnet that attracts metals with the help of electricity. Perfect, now your kids will pay attention. You will need: Batteries: one 9V, one 6V, one 1.5V. In this project, you will explore whether the strength of an electromagnet changes with the number of turns in the magnet's coil. As you saw in the last experiment, electric current flowing through a wire produces a magnetic field. Experiment 1: Electromagnetic Suction.
