No, you should never put a metal handle or any metal parts on an electric frying pan in a microwave oven. Microwaving metal can be extremely dangerous and may cause a fire or damage to the microwave.
Microwaves work by emitting electromagnetic waves that excite the water molecules in food, causing them to heat up. When metal is placed inside a microwave, it reflects and traps the microwaves, leading to a concentration of energy in a localized area. This can result in arcing, sparks, and intense heat, which can cause a fire or damage the microwave oven.
If your electric frying pan has removable metal parts, such as a metal handle, be sure to remove them before microwaving any food. Always follow the manufacturer's instructions and guidelines for using your electric frying pan, and never attempt to use it in a microwave unless specifically stated that it is microwave-safe.
To safely use an electric frying pan, stick to its intended purpose of cooking on a stovetop or other appropriate heat sources, and avoid using it in a microwave oven.
