b. conductor location in the magnetic field
c. flow of current in the conductor
d. all the three
3. If the magnitude of the flux density is small, the force on the conductor is:
a. small
b. great
c. does not depend on the flux density
4. Which of the following is true:
a. the smaller the conductor the bigger the magnetic force on it
b. the smaller the conductor the smaller the magnetic force on it
c. the longer the conductor, the greater the force exerted on it
d. the longer the conductor the smaller the force exerted on it

Translate into English.
1. Если проводник помещен в магнитное поле и через это поле проходит ток, то проводник начинает двигаться.
2. Только та часть проводника, которая расположена в магнитном поле, испытывает на себе силу тока.
3. Сила, приложенная к проводнику, зависит от напряженности магнитного поля, длины проводника, находящегося в магнитном поле и величины тока, протекающего в проводнике.
4. Катушка параллельного возбуждения состоит из многих витков тонкой проволоки и соединена последовательно с реостатом возбуждения.
5. Поскольку момент пропорционален магнитному потоку и току якоря, поток в двигателе смешанного возбуждения будет больше, чем в двигателе с параллельным возбуждением из-за дополнительного потока, произведенного обмоткой последовательного возбуждения.
6. В двигателе смешанного возбуждения момент увеличивается больше, чем в двигателе параллельного возбуждения, потому что общий поток увеличивается, а не остается постоянным, как это происходит в двигателе с параллельным возбуждением.
7. В двигателе последовательного возбуждения увеличение момента приводит к увеличению как тока якоря, так и потока, производя намного большее повышение момента.
