Question

Find the odd one out:
Magnetite, Magness, Magnesia, Bar magnet
A. Magnetite
B. Magness
C. Magnesia
D. Bar magnet

Answer 1

Hint: Iron mineral is the wellspring of essential iron for the world's iron and steel ventures. It is in this way necessary for the creation of steel, which this way is essential to keep up a solid modern base. Practically all (98%) iron mineral is utilized in steelmaking. Iron metal is mined in around 50 nations.

Complete step by step answer:
Iron metal is a mineral substance which, when warmed within the sight of a reductant, will yield metallic iron (\[Fe\]). It quite often comprises of iron oxides, the essential types of which are magnetite (\[F{{e}_{3}}{{O}_{4}}\]) and hematite (\[F{{e}_{2}}{{O}_{3}}\]).
Magnetite, Magness, Magnesia, are metal of Iron. Though a Bar magnet is a magnetic substance called magnet. Magnetite is a stone mineral and one of the fundamental iron metals, with the concoction equation \[F{{e}_{3}}{{O}_{4}}\].

It is among one of the oxides of iron, and is ferrimagnetic; it is pulled into a magnet and can be polarized to turn into a lasting magnet itself. It is the most magnetic of all the usually happening minerals on Earth.

The seven most significant of these delivering nations represent around seventy-five per cent of absolute world creation. Australia and Brazil together overwhelm the world's iron mineral fares, each having around 33% of absolute fares.

The correct answer is D.

Note:
A bar magnet is a rectangular bit of an item, composed of iron, steel or some other ferromagnetic substance or ferromagnetic composite, that shows perpetual magnetic properties. It has two poles, a north and a south shaft with the end goal that when suspended openly, the magnet adjusts itself, so the northern shaft focuses towards the magnetic north post of the Earth.
