How many different kinds of metal can electromagnetism pick up and at what voltage?

∙ 16y ago
Certain materials are strongly magnetic, such as nickel, iron, cobalt, and their alloys. Whether or not a particular electromagnet can pick up a particular piece of metal (assuming it in one of those on the list) depends on the size and weight of the metal and the strength of the electromagnet. http://en.wikipedia.org/wiki/Magnetism

Low voltage does not imply low hazard?
This depends on your definition of hazard, and low voltage for that matter. A car battery is 12 volts, which is not enough to kill someone, but it is certainly enough to melt metal if you drop a metal tool across both positive and negative terminals. The melting metal can cause burns, etc.
Why current transformer should be grounded?
If there is a short circuit between the transformer's high-voltage windings and its core (or any other metal parts, come to that) the fault will be recognised by the high-voltage supply's protective system, which will quickly disconnect the high-voltage line. For this to happen, the metal parts of the transformer, including its core and metal container, must be earthed or grounded to provide an electrical path back to the source of the high voltage.
What is the purpose of ballast in lighting?
The ballast is a transformer that steps the voltage up higher than its incoming voltage. This is usually used with flourescent, metal halide, & sodium vapor lights. The higher voltage is needed to 'excite' the gases within the bulbs and make the molecules bounce around and give off light.
Why power rating of capacitor is reactive in nature?
A capacitor is composed of metal plates. Voltage is applied to one, which causes electrons to build up on the other. This is reactive in nature, thus a capacitor is reactive. It stores a charge, and releases this charge when the voltage decreases.
What is the Working principle of proximity sensor?
there are different types of proximity sensors namely inductive capacitance and infrared. the working principle of inductive proximity sensor is, it consists coil, oscillator, detector and trigger circuit. when current flows through a coil magnetic field will be generated and when the metal get contact with that field the voltage is induced in the metal the detector detects this loss in voltage and triggering circuit will give the contact output... praveen achalkar MCF mangalore

What are the different kinds of saws?
There are several different kinds of saws that give you different cuts as well as are designed to handle certain materials. Different kinds of saws include table saws, power hand saws, band saws, miter saws, metal cutoff saws, and circular saws.
What are the 3 kinds of element?
The 3 kinds of elements are metal, non-metals, and metalloids.
What are the particles present in metallic bonding?
There are many different types of metal, so it depends on the metal. If it is a metal such as pure copper, it is made up of only copper atoms. If it is a metal like bronze, it is made up different kinds of atoms like copper and tin. If it is an alloy, there are many different kinds of atoms contained within the metal.
