The position is the strength of the magnetic field strongest is is the place where the magnetic field leaves, being point A.

<h3>What generates a magnetic field?</h3>

When an electrically charged particle moves, it creates a magnetic field. According to the laws of electromagnetism, this magnetic field originates from the variation of the electric field strength.

In the region of the poles we see that the lines of magnetic induction are closer to each other, therefore, we consider that close to the poles the magnetic field is more intense.

When 3.0g of magnesium is burnt in 2.00g of oxygen, 5.00g of magnesium oxide is produced. What mass of magnesium oxide will be f
guajiro [1.7K]

Answer: -

8.00 g

The law of conservation of mass

Explanation: -

When magnesium burns in air it combines with oxygen to form magnesium oxide.

The mass of the product is the mass of the magnesium oxide.

The mass of the reactant is the mass of the magnesium + mass of the oxygen.

Since matter cannot be created or destroyed according to the law of conservation of mass,

Mass of Magnesium oxide formed = mass of magnesium reacted + mass of oxygen reacted

= 3.00 g + 5.00 g

= 8.00 g
