A man has built such a precise replica of Thor’s hammer that only he is “worthy” enough to lift it.

Allen Pan built a replica ‘Mjolnir’, which in the Marvel comics and films can only be lifted by Thor or somebody deemed “worthy” enough, otherwise it is too heavy to lift.

The engineer made the device through placing a microwave oven electromagnet in the hammer’s head, which created a very strong magnetic field, according to C Net.

He then made the handle touch-sensitive, meaning when someone holds the hammer the electromagnet turns on.

However, Mr Pan also devised a fingerprint sensor which can turn off the magnet. By programming it to his fingerprint, Mr Pan is the only one who can pick it up as his fingerprints disable the magnet.
