Move the compass slowly along a semicircular path above the bar magnet until you’ve put it on the opposite side of the bar magnet. Describe what happens to the compass needle. The white lead of the needle faces the South part of the magnet in a perpendicular way. When the needle is facing the center of the magnet‚ the lead turns to a 90 degree angle

Ferro-Para-Di-Magnetism Magnetism is defined in the dictionary as the class of phenomena exhibited by a magnetic field. In physics there are a few types of magnetism. In this paper only three types will be covered which are ferromagnetism‚ paramagnetism‚ and diamagnetism. Ferromagnetism is considered the strongest type of magnetism‚ as it is a permanent magnet. A permanent magnet is one that remains a magnet after being magnetized by an outside magnetic field. Ferromagnetism is a type of magnetism that

Physics Lab Report: Magnetism Aim: To compare the ratio of the magnetic length‚ the geometric length and magnetic field strength of different shaped magnets. Materials: * A Bar Magnet * A Horse Shoe Shaped Magnet * A Cylindrical Magnet * A Compass * Pencil * Ruler * A Wooden Board * 4 Needles * A bunch of Needles/pins * A3 Size paper Procedure: 1. We took a wooden board and 4 needles‚ which we hammered to the 4 corners of the board. 2. We

Electricity and Magnetism History Electromagnetism Originally electricity and magnetism were thought of as two separate forces. This view changed‚ however‚ with the publication of James Clerk Maxwell’s 1873Treatise on Electricity and Magnetism in which the interactions of positive and negative charges were shown to be regulated by one force. There are four main effects resulting from these interactions‚ all of which have been clearly demonstrated by experiments: 1. Electric charges attract

Strings of holiday lights can be designed in one of two ways. In some strings of lights‚ each light is connected to the others along a single wire (in series). In others‚ each light is attached to its own wire (in parallel). Suppose a single light bulb burns out. How do you think

What is Magnetism? Properties of Magnets: Magnet: any material that attracts iron and materials that contain iron Magnets attract iron and materials that contain iron. magnets attract or repel other magnets. In addition‚ one part of a magnet will always point north when allowed to swing freely. Magnetic Poles: Magnetic Pole: any magnet with 2 ends‚ each is called a magnetic pole. Magnetic poles that are unlike attract each other and magnetic poles that are alike repel each other. Magnetic

speaking about magnetism and its use in our everyday lives‚ you can learn the SECRETthe secret of magnetism! A true scientist would be glad to share his secrets through experimentation. Thus‚ I will share the secret with you. It begins with sciencephysics‚ to be exact: matter and energy‚ conduction and induction‚ magnetizing and demagnetizing. All will be explained in my science project. More importantly‚ to discover through experimentation that the secret behind magnetism could be its power

discussion on magnetism to Thales of Miletus‚ who lived from about 625 BC to about 545 BC.[1] Around the same time‚ in ancient India‚ the Indian surgeon‚ Sushruta‚ was the first to make use of the magnet for surgical purposes.[2] There is some evidence that the first use of magnetic materials for its properties predates this‚ J. B. Carlson suggests that the Olmec might have used hematite as a magnet earlier than 1000BC[3] [4] In ancient China‚ the earliest literary reference to magnetism lies in a 4th-century
