A research team at the University of Toronto in Canada has developed a set of miniature magnet-powered tools that could ...

A University of Toronto Engineering team has collaborated with researchers in the Wilfred and Joyce Posluns Centre for Image ...

A new prototype is laying claim to the title of smallest, lightest untethered flying robot. At less than a centimeter in ...

Robotic surgical tools (around 8 millimetres in diameter) have been used for decades in keyhole surgery for other parts of ...

Tiny magnetic "flowers" engineered by physicist Anna Palau are redefining how we manipulate magnetic fields. These ...

A flower-shaped structure only a few micrometers in size made of a nickel-iron alloy can concentrate and locally enhance ...

Point the fingers of your right hand in the same direction as the current is flowing in the coil. Your thumb points to the north pole of the electromagnet. The magnetic field produced by the ...

A research paper by scientists at the University of Macau proposed a novel multi-section magnetic soft robot maneuvered by an associated collaborative multirobot navigation system with magnetic ...

A coil with an iron core is called an electromagnet. The iron core increases the coil’s magnetic field strength. A simple electromagnet is made by coiling wire around an iron nail. An iron core ...
