Answer
permanent magnet
Explanation
## Step1: The problem is asking us to identify the type of magnet that would be used to hold up a picture on a fridge door. This implies that the magnet must have the ability to maintain its magnetic properties over time without requiring an external magnetic field.## Step2: A permanent magnet is a type of magnet that maintains its magnetic properties over time and does not require an external magnetic field to remain magnetized. This makes it suitable for holding up a picture on a fridge door.## Step3: An induced magnet only becomes magnetized in the presence of an external magnetic field and loses its magnetism when the external field is removed. This makes it unsuitable for holding up a picture on a fridge door.## Step4: The term "elealiomagnet" appears to be a typographical error and does not correspond to any known type of magnet.## Step5: A temporary magnet is similar to an induced magnet in that it only maintains its magnetism for a short period and requires an external magnetic field to remain magnetized. This makes it unsuitable for holding up a picture on a fridge door.## Step6: Therefore, the correct type of magnet to use for holding up a picture on a fridge door is a permanent magnet.#
