sound energy is first converted in to electrical energy by its batteries and then converted in to microwaves by the phones antenna and then it is sent to the nearest cell tower at a particular frequency. 3.A cell tower boosts a radio wave signal using what type of energy? At the cell tower the microwaves are turned into electrical energy and then electrically boosted and turned back into microwaves to be sent to the receiving phone. 4. After the message is boosted at a cell tower‚ state two

TYPES OF MAGNETIC MATERIALS Paramagnetic materials have a small‚ positive susceptibility to magnetic fields. These materials are slightly attracted by a magnetic field and the material does not retain the magnetic properties when the external field is removed. Paramagnetic properties are due to the presence of some unpaired electrons‚ and from the realignment of the electron paths caused by the external magnetic field. Paramagnetic materials include magnesium‚ molybdenum‚ lithium‚ and tantalum
