Are magnets more powerful than electromagnets?
Electromagnets have the main benefit of manipulating their magnetic pull strength – both by turning the magnet on or off and by adjusting the current. They also feature greater pull strength than permanent magnets. Some estimates place the largest electromagnet at 20 times stronger than the strongest permanent magnet.
How do magnets lose their strength?
As the temperature increases, at a certain point called the Curie temperature, a magnet will lose its strength completely. Once the metal cools, its ability to attract magnets returns, though its permanent magnetism becomes weak. In general, heat is the factor that has the most effect on permanent magnets.

Is digital door lock safe?
Electronic door locks are safe, but only as much as, if not lesser than, normal, non-electronic, keyed locks. Furthermore, almost all of the locks that use fingerprints, Wi-Fi or Bluetooth tend to cease functioning in the event of a power outage, in which case a person has to use a backup key to unlock their door.
