Grade 5 How are electricity and magnetism related Uses of Electricity and Magnetism National Geographic Video Electromagnetic field Electromagnetic fields are everywhere around us An electromagnetic field is an invisible magnetic force that exists around any conductor that is carrying electricity . Magnetism is the property of attracting iron by a magnet.. A magnet is an object made of certain materials like iron which can create a magnetic field around it. If there are things made of iron in this field (region) they are attracted by the magnet.. A unit of measure of . magnetic field strength. , the _____________, is named after him.. connected. oersted. Electricity and Magnetism. How can an electric charge create a magnetic field?. . How is an electromagnet controlled?. The Periodic Table. Everything in the world is made up of . elements. Invented by: . Dimitri. . Mendeleeve. There are a total of . 111 known elements.

Comparison of 3d and 4d magnetism. 3d transition metals Fe, Co, and Ni are ferromagnetic, however no 4d or 5d are ferromagnetic (except reports of . Intro video. Properties of Magnets. They attract ferromagnetic materials. Iron, nickel, cobalt. They have magnetic poles. Like poles repel. Opposite poles attract. Magnetic Poles. Magnetic Fields. The area . What is magnetism?. Force of attraction or repulsion due to electron arrangement. Magnetic forces are the strongest at the poles. Magnets have two poles: North and South. Magnetic poles and fields. Magnets always have two poles. Discuss the nature of magnets, particularly with reference to poles.. Demonstrate the properties of magnets.. Demonstrate and discuss the magnetic effect of electric current.. Discuss the uses of electromagnets.. Often cheap relative to other geophysical techniques.. Can be measured with ground-based or airborne equipment.. Not usually very useful when looking at sedimentary structures. (We’ll see why later!). Magnets and magnetic fields.
