Force exerted by magnets when they attract or repel each other. - MAGNETISM, An object that is capable of producing magnetic field. - MAGNETS, KINDS OF MAGNET - ARTIFICIAL AND NATURAL, Materials that are attracted by magnets. - FERROMAGNETIC, Slightly attracted by a magnetic field - PARAMAGNETIC, Slightly repelled by a magnetic field and do not retain magnetic properties when the external field is removed. - DIAMAGNETIC, Magnesium, Molybdenum, Lithium, and Tantalum - PARAMAGNETIC, Copper, Gold, Silver - DIAMAGNETIC, Usually the magnetic domains are randomly arranged. - INDUCED MAGNETISM, It was discovered that running current through a wire produced a magnet - ELECTROMAGNETISM, cause of all magnetism - CURRENT, F - force - N, Q - charge - C, V - speed of charge - M/S, B - magnetic field - T, 𝜃 - angle between v and B - °, the process of using magnetic fields to produce voltage, and in a complete circuit, a current. - ELECTROMAGNETIC INDUCTION, Discovered “Electromagnetic Induction”. - MICHAEL FARADAY, Discovered that the electric current in a wire can deflect a magnetized compass needle. - HANS-CHRISTIAN OERSTED, current changes direction with charge in magnet motion - MAGNETIC INDUCTION, is any area that has a magnetic field passing through it. - MAGNETIC FLUX, "Φ" - Magnetic Flux, A - Area, It states that the electromotive force induced in a wire is proportional to the rate of flux in a loop. - FARADAY’S LAW, ε - Induced voltage, Ν - Number of loops, ∆"Φ" - Change in Magnetic Flux, ∆"t" - Change in Time, V - Volts, gives the direction of the induced emf and current resulting from electromagnetic induction - LENZ’S LAW, Designed one of the first practical devices to transfer Alternating Current power. - William Stanley Jr., commonly used in homes and businesses. - ALTERNATING CURRENT, It is a device that increase or decrease the alternating voltage in electrical power applications. - AC TRANSFORMER, current which flows in one direction only. - DIRECT CURRENT, APPLICATION OF DC CURRENT - FLASHLIGHT, CELLPHONE & LAPTOP, Property of light that occurs when light bounces back as it hits a surface. - REFLECTION, States that the angle of reflection (θ_r) is the same as the angle of incidence (θ_i). - LAW OF REFLECTION, - Light strikes in a smooth surface. - REGULAR REFLECTION, - Light strikes in a rough surface. - DIFFUSED REFLECTION, Reflective surfaces made up of glass. - MIRRORS, flat surfaces that reflect light and form an image of an object brought in front of it. - PLANE MIRRORS, This uses at least two rays to locate and describe the image. - RAY DIAGRAMMING TECHNIQUE, - a mirror with curve reflective surface - CURVED MIRROR, have their reflective surfaces bent outward. - CONVEX MIRROR, have their reflective surfaces bent inward. - CONCAVE MIRROR, Bending of light waves as they enter or cross the boundary between two media with different densities. - REFRACTION, – he described the relationship of the angle of incidence to the angle of refraction. - Willebrord Snellius (Snell), produced by moving electric charges. - Magnetic Fields, produced by charge particles - Electric Fields, It is made up of transparent material such as glass or plastic with a refractive index. - LENSES, It is also known as CONVERGING LENS - CONVEX LENS, Thicker at the center than the edges. - CONVEX LENS, It is also known as DIVERGING LENS - CONCAVE LENS, Thinner at the center than the edges - CONCAVE LENS, a hole which size can be changed to allow light to pass out the lens and into the camera. - Aperture, a doorway that will allow light to pass through out of the aperture. - Shutter, transforming image to save picture or video in the SD Card. - Charge-Coupled Device (CCD),
