For Rutherford's alpha particle scattering from gold, with mass of 197, the reduced mass is very close to the mass of the alpha particle: = + = For lighter aluminium, with mass 27, the effect is greater: = + = a 13% difference in mass. Rutherford notes this difference and suggests experiments be performed with lighter atoms.
If another coil is used to measure the magnetic field (acting as a magnetometer), the change in the magnetic field due to the metallic object can be detected. The first industrial metal detectors came out in the 1960s. They were used for finding minerals among other things. Metal detectors help find land mines.
Most metals, including gold, silver and aluminum, are nonmagnetic. A large diversity of mechanical means are used to separate magnetic materials. [2] During magnetic separation, magnets are situated inside two separator drums which bear liquids. Due to the magnets, magnetic particles are being drifted by the movement of the drums.
An evil sea lion named Goldflipper (voiced by Jim Cummings) creates a giant gold magnet that steals golden teeth, which he calls the "Molar-Acoustic-Synctro-Bicuspid-Dental-Magnetic-Electro-Platt-Conductive-Postiviser". Secret goes undercover as a Squirrely Girly Scout to thwart Goldflipper's evil plan and recover all the stolen teeth.
Panning for gold was the simplest method of recovering gold, but mostly used for prospecting since it was slow. A faster way was by a rocker box or by sluicing. Dirt was filled into the box or sluice together with water and rocking movements or gravity would make the gold particle go to the bottom whereas sand and fine gold particles would flow ...
A gold pan. Gold prospecting is the act of searching for new gold deposits. Methods used vary with the type of deposit sought and the resources of the prospector. Although traditionally a commercial activity, in some developed countries placer gold prospecting has also become a popular outdoor recreation. Gold prospecting has been popular since ...

Magnetism is the class of physical attributes that occur through a magnetic field, which allows objects to attract or repel each other.Because both electric currents and magnetic moments of elementary particles give rise to a magnetic field, magnetism is one of two aspects of electromagnetism.
