Lab Worksheet 1. Explain what it means when we say a substance is magnetic. It means that the substance has a lot of electrons that are creating magnetic fields. 2. Discuss the relationship between electric and magnetic fields. An electromagnetic wave generates both‚ electric and magnetic fields. A magnetic field can be induced by a wire conducting an electric current and a electric field can be induced in a coiled piece of copper wire if a magnet is moved through the center of the coiled wire

This report will be done on the theory of Electromagnetism. Electromagnetism is the force that combines electricity and magnetism. Electromagnetism is found in everyday things that shape our lives. It is the cleanest force used to make energy today‚ and it is used in almost every home appliance that is in a standard middle classed home. The E-M force is the most commonly under looked force that helps us live. Without Electromagnetism‚ we would be falling through floors‚ literally! E-M force can be

Unit 1 What is inside an atom? * A positively charged nucleus composed of protons and neutrons * Electrons that surround the nucleus What are isotopes? Isotopes are atoms with the same number of protons and different numbers of electrons How do we represent different atoms? What is specific charge? The specific charge of a particle is defined as its charge divided by its mass What keeps protons and neutrons in a nucleus together? A stable isotope has nuclei that do not disintegrate

Electromagnetism From Wikipedia‚ the free encyclopedia Jump to: navigation‚ search Electromagnetism is the physics of the electromagnetic field‚ a field that exerts a force on particles with the property of electric charge and is reciprocally affected by the presence and motion of such particles. A changing magnetic field produces an electric field (this is the phenomenon of electromagnetic induction‚ the basis of operation for electrical generators‚ induction motors‚ and transformers). Similarly

Electromagnetism and it’s Impact on our Health Car By: Dalia Newman Course: Grade 12 Physics Teacher: Mrs. Chocron Due: Friday April 15 2011 Electromagnetism and it’s Impact on our Health Care Electromagnetism is one of the four fundamental interactions of nature. It is the force that causes the interaction between electrically charged particles; the areas in which this happens are called electromagnetic fields. It

IGCSE MAGNETISM AND ELECTROMAGNETISM DEFINITIONS AND CONCEPTS HARD AND SOFT MAGNETIC MATERIALS: Materials‚ which are difficult to magnetise and de-magnetise. Soft materials are easy to magnetise and de-magnetise. MAGNETIC FIELD: The area around a magnet where another magnet would feel a force. MAGNETIC FIELD LINES: Show the direction of the magnetic field. The lines run from North to South. Where the field is strong‚ they are close together. INDUCED MAGNETISM: A magnetic material can

Magnets. How do they work? How does the number of coils affect electromagnetism? Hypothesis: When there is a flow of moving electrons‚ a magnetic field is created. We use the equation F = NIlB (Force = Number of coils x Current x Length of Wire x Magnetic Field Strength) to work out the magnetic force produced in a wire when there is an electric current present. Using this equation we can see that increasing the length of the wire (amount of coils) gives a larger force. So increasing the amount
