This movement creates electric currents, which in turn produce the magnetic field.<br /><br />## Step 2<br />The statement "Earth's core is composed of magnets" is incorrect. The Earth's core is not composed of magnets, but rather of iron and nickel.<br /><br />## Step 3<br />The statement "Earth's core is composed of iron and nickel" is correct. The Earth's core is indeed composed of iron and nickel.<br /><br />## Step 4<br />The statement "The outer core is solid" is incorrect. The outer core is actually liquid, not solid.<br /><br />## Step 5<br />The statement "The inner core is liquid and moving" is incorrect. The inner core is actually solid, not liquid.
