Building an Electromagnet. Science Notebook - Magnetism 1. You have probably played with magnets at some point and are already at least a little familiar with them. But you may not know that magnetism and electricity are related. In these experiments, we will study some of the properties of magnets and magnetism, and we will also see how a magnet can be used to produce electricity. Observing the Poles of a Bar Magnet Materials Needed: Two bar magnets. (NOTE: Some magnets are labeled “N” and “S” on the ends. These markings designate the “poles” of a magnet. However, if your bar magnet is not marked, that doesn’t mean it doesn’t have poles. Procedure: Place one of the magnets on a smooth surface such as a table.
What Happened: Every magnet is surrounded by an invisible field called an “magnetic field”. Going Further: Try bringing your two magnets together in different places to see whether there are other places where they attract and repel. Demonstrating that a Compass Needle is a Magnet Now, bring one end of the bar magnet to the compass. Magnetism experiment. Amazing Discovery With Magnets. Physics Zone - Lenz's Law. Magnet Man - Cool Experiments with Magnets. Cool Experiments with Magnets This web site is devoted to magnetism and the cool experiments you can do with permanent magnets and electro-magnets. Some of the experiments are very basic - things you've done since third grade. Others are unique - perhaps you hadn't thought of doing some of these before, or had difficulty in trying to set them up. Lists of the materials needed for the demonstrations, directions on how to assemble them, instructions on how to show them, and notes on how they work are all here for you.

Safety Considerations IMPORTANT! What is attracted to magnets? Electromagnets What is an electromagnet? Generators What happens when a wire moves with respect to a magnetic field? Protector: How Can Magnetic Materials Be Shielded From a Magnetic Force Field? Problem How can magnetic materials be shielded from a magnetic force field? Materials scissors ruler cardboard 2 pencils masking tape bar magnet 10 paper clips stainless steel cake-server Procedure Cut two 8-inch × 4-inch (20-cm × 10-cm) cardboard pieces. Results The paper clips are first pulled up and cling to the bottom of the cardboard-and-air sandwich. Why? The magnetic lines of force from the magnet pass through the cardboard and air, as indicated by the attraction of the paper clips toward the magnet.
