Question

List the four methods needed to prevent EMI:

Answer 1

To prevent Electromagnetic Interference (EMI), one can use hands-free devices, keep mobile phones away from the body, avoid using cellphones in cars without external antennas, and ensure electrical devices are properly grounded.

Step-by-step explanation:

To prevent Electromagnetic Interference (EMI), various methods can be employed. These can be simple behavioral changes or technical solutions, such as:

• Using hands-free devices to decrease radiation exposure to the head.
• Keeping the mobile phone away from the body to reduce direct exposure to electromagnetic fields.
• Avoiding the use of a cellphone in a car without an external antenna, as it can amplify the EMI due to the metal structure of the car acting as a Faraday cage.
• Grounding electrical devices to manage electromagnetic induction and prevent leakage currents that can cause shocks or interfere with other devices.
