Final answer:
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.
