Do refrigerator magnets increase the energy consumption of a refrigerator due to induction?
No. A refrigerator magnet does not have a strong enough magnet field to affect your motor. Also the motor is mounted either at the top of bottom of your fridge. Far enough away from the outside of the door.

My side-by-side fridge, which is about 8 years old, uses 70 watts on average. When the compressor is actually on, it draws about 200 watts after an initial spike of ~400 watts…. The fridge draws 5 watts when idle.
it is a magnet and you just stick it to your fridge
Sure. The more the door is opened the more it needs to cool down, so the more power it will use.
The term "refrigerator magnet" is ambiguous and may refer to anynumber of types of magnets. However, typically a refrigeratormagnet is going to be relatively weak and made of …the mostinexpensive materials available. Hard refrigerator magnets arelikely iron. Flexible refrigerator magnets are made of bondedferrite powders; barium ferrite is among the most common. In general classification, a refrigerator magnet is a permanentmagnet.

Wikipedia defines: "Electromagnetic induction is the production of voltage across a conductor situated in a changing magnetic field or a conductor moving through a stationary …magnetic field." You can increase the prodution of voltage (in a transformer) by increasing the number of turns (changing the turns ratio). If you are attempting to induce a voltage on a wire, placing the wire closer to the source of the magnetic field will increase the magnetic flux, thus increasing the voltage.

Because most refrigerators are made of ferromagnetic materials, and ferromagnetic materials are attracted to magnets.
A magnet is a substance that is made of iron. The molecules in it are arranged in a way different than most magnets which is why the magnet has a tendency to attract materials… more. Instead of the fridge magnet having a distinct north or south pole attraction, the fridge magnet has both alternating. This actually gives a stronger force of attraction. When the magnet is brought in contact or brought close to the fridge, the force between the north and south poles of the body of the fridge and the magnet attract each other, and the alternating poles on the magnet attract as well, giving that extra attraction.
Yes , you can put magnets on a fridge door
to seal it from ambiant temp out side the fridge
