What the video says
A magnetar is a neutron star with an extremely powerful magnetic field. Robert Duncan and Christopher Thompson proposed them in 1992.
Magnetars are around 20 kilometres in diameter and have a mass of about 1.4 solar masses.
A tablespoon of magnetar material has a mass of over 100 million tons. Your IKEA table was not rated for this.
A magnetar narrows a hydrogen atom dramatically.
Most observed magnetars rotate once every two to ten seconds. Typical neutron stars spin one to ten times per second.
Starquakes disturb the magnetic field, causing gamma-ray flares in 1979, 1998, and 2004. Credit cards would not survive the trip.
Most neutron stars simply lack the ambition.
Magnetar magnetic fields decay after about 10,000 years. Then strong X-ray emission ceases.
