2. Electromagnetism Electromagnetism is the physics of the electromagnetic field a field that encompassing all of space which exerts a force on particles that posses the property of electric charge. The magnetic field is produced by the motion of electric charge.

3. Electromagnetism The magnetic field causes the magnetic associated also with magnets. Electromagnetism comes from the fact that magnetic and electrical forces are involved. Electromagnetism is a science that deals with observations relating to electricity and magnetism.

4. Electromagnetism The magnetic field at any point is described in terms of the force that exerts on a moving charge. Electromagnetism is essentially the foundation for all or electrical engineering

5. Electromagnetism Electromagnetic spectrum is just a name used by scientists to categorize different types of radiation. Radiation is energy that travels and spreads out as it becomes visible light that comes from a lamp in your house or radio waves that come from radio station are examples of two types of electromagnetic radiation.

6. Electromagnetism There are many problems with energy use and battery power today. Many devices especially portable devices are battery powered for example ipods, laptops, cameras, and cell phones. The problem is each device has its own power adapter.

7. Electromagnetism Each one of them are different from each other. Energy is used a lot daily in every single household even outdoors. Whether its stores even if its restaurants each conserves a lot of energy.

8. Electromagnetism Physicists plan to try wireless battery charging which involves electromagnetism. Their idea is that the recharge device and the receiver would be on the same frequency similar to how a radio picks up only one channel at a time. The energy would mostly go straight to the intended battery.

9. Electromagnetism Some of the electromagnetic energy would go somewhere else and it’s believed that it wouldn’t harm people nothing that humans could endure strong magnetic fields. There’s one called evanescent coupling which allow electronic gadgets to start charging themselves as soon as their owners walk into their homes. One idea to make a wireless charger is to use electromagnetic induction which posses an electric current through a coil to create a magnetic field.

10. Electromagnetism That induces a current in a neighboring coil. This is the same way devices like electric math busters are charged. It has been proposed as a basis universal recharge pad. The pad could power up all gadgets. Another name for the rechargeable pad is wild charge. The device requires a single AC power cord and then can reportedly recharge any device you lay on top of its surface for example cell phones

11. Electromagnetism The wireless charger is very useful and has a positive effect in many ways. It’s less to worry about when it comes finding the correct charger. Technology like this can allow us to cut some of the cords used. The new cell phone charger technology will set the stage for a whole new generation for tools that could be wirelessly charged while inside the body. The medical device companies wouldn’t mind that concept the wireless charger would also prevent people from having health problems.

12. Electromagnetism Cell phones affect the central nervous systems. Living creatures are being found to be influenced by the most delicate fields of electromagnetic energy. But the problem with the wireless charger is that when charging a cell phone the devices and charger must be in close proximity with each other in order to work efficiently. Electromagnetism and magnetic field are used daily in electronic devices. Whether its cell phones, microwaves, refrigerators, even a television. Electromagnetic fields help with finding better ways of charging electronic devices.

13. Electromagnetism The solution to this problem is to make sure all electromagnetic energy is used correctly. Especially cell phones when using the wireless pad stay off the phone while it’s charging instead when you charge with a wire you can still communicate with someone on the phone.
