In your project select a high-tech device (include several illustrative images), and why you chose that device. List the physics principles that apply to the operation of your device, and give specific examples of each. Include at least 3 relevant physics equations in your examples. Use a few images to illustrate your examples. Include at least 2 sample calculations for your device. Most high-tech devices involve electricity or magnetism in some way, and thus electromagnetic fields. Sometimes electromagnetic fields can create interference or other undesirable effects in your device. Identify any electromagnetic fields that exist in your high-tech device and describe any shielding used to block out unwanted electromagnetic fields.
