Investigating Factors that Affect the Strength of an Electromagnet Aim: To investigate the factors‚ which affect the strength of an electromagnet‚ also known as it’s‚ pick up power. Predictions: The more coils of wire used on the electromagnet then the greater number of paper clips picked up. Also The greater the current the greater the number of paper clips picked up. There will also be a limit to the amount of magnetism created and how many paper clips can be picked up

Physics in Everyday Life 1 Just about everything you do from moving to eating to listening to music involves physics. Now that I have really explored them I think it is hard to go about our day and not do something that involves physics. Some of the things I will talk about are getting out of bed‚ the eye and how eye glasses help a person see better‚ speakers‚ the Frisbee‚ sailing‚ and the pulleys I use to get my jeep unstuck in the mud when I ride in the woods.

magnetic properties‚ you can use a magnet to separate the mixture. Cobalt‚ iron and nickel all have magnetic properties. Note that not all metals are magnetic and magnetism is not a method to separate metals from non-metals. Gold‚ silver and mercury are examples of non-metal substances. Magnetism is however a way to separate magnetic substances from non-magnetic substances is. Magnetism as a separation method is done by taking any magnetic force (Electro magnets included) and moving it above an insoluble

A Description of Cochlear Implants A Cochlear Implant is a specialized hearing device that consists of both a surgically-implanted and external component used to simulate natural hearing. This device is used to treat people with severe and profound hearing loss. The implanted component is placed under the skin‚ behind the patient’s ear‚ and connected to the auditory nerve of the brain. The Cochlear Implants are designed to receive sounds and convert them into electrical signals that bypass
