<u>Answer</u>:
1. <em>The student could increase the number of loops of wire around the iron core. </em>Increasing the number of windings will increase the strength of the electromagnet also known as the magnetomotive force.
2. <em>The student could use a bigger battery so that the voltage is increased. </em>Thus, according to Ampere's Law, the magnetic field around the current-carrying wire will also increase as it is directly proportional to the current's strength.
Answer:
If two tectonic plates collide, they form a convergent plate boundary. Usually, one amongst the converging plates will move beneath the opposite, a process called subduction. ... The new magma (molten rock) rises and will erupt violently to make volcanoes, often building arcs of islands along the convergent boundary. When two plates are moving far from one another, we call this a divergent plate boundary. Along these boundaries, magma rises from deep within the world and erupts to make new crust on the lithosphere. Most divergent plate boundaries are underwater and form submarine mountain ranges called oceanic spreading ridges. While the method of forming these mountain ranges is volcanic, volcanoes and earthquakes along oceanic spreading ridges aren't as violent as they're at convergent plate boundaries.
