Keep a strong magnet around, and you can magnetize some types of steel with a couple minutes of work.
The magnetized beads are sedimented using a strong magnet in the washing station and washed several times followed by addition of isoluminol-conjugated anti-human IgG and again incubated 9.5 minutes at 37°C.
After washing, IgG antibody-binding beads were removed by incubation with IgG-coated iron oxide particles, and the magnetized TentaGel beads were removed using a strong magnet.
Paramagnetism, kind of magnetism characteristic of materials weakly attracted by a strong magnet, named and extensively investigated by the British scientist Michael Faraday beginning in 1845.
Make sure that it is magnetic and make sure that you have a strong magnet.
The cell/bead suspension was placed on a strong magnet and the ferrous beads with cells attached were removed by magnetic adhesion.
The performance involved putting a strong magnet on top of a TV hooked up to speaker to manipulate the magnetic field, which created both visuals and a low hum.
Phoenix has become an especially strong magnet.
In 1881, Emil Warburg, a German physicist, placed a piece of metal near a strong magnet.
And like a strong magnet, these receptors don't easily let things go.
One is a very strong magnet made of neodymium, iron and boron (NIB).
