Is opposite to that of the main pole ahead.<\/p>\n<p>Interpoles are auxiliary poles located between the main poles of a DC generator. They are used to reduce sparking at the brushes. The polarity of the interpoles is opposite to that of the main pole ahead. This helps to ensure that the current in the armature winding always flows in the same direction, which reduces sparking.<\/p>\n<p>Option A is incorrect because the polarity of the interpoles is opposite to that of the main pole ahead, not the same.<\/p>\n<p>Option B is incorrect because the polarity of the interpoles is opposite to that of the main pole ahead, not the <div class=\"youtube-subscribe-container\">\r\n        <a href=\"https:\/\/www.youtube.com\/channel\/UCNHT8lW-JmLC68rjBfZhdkg?sub_confirmation=1\" target=\"_blank\" class=\"youtube-subscribe-button\">\r\n            <span class=\"youtube-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 576 512\">\r\n                    <path d=\"M549.7 124.1c-6.3-23.7-24.8-42.3-48.3-48.6C458.8 64 288 64 288 64S117.2 64 74.6 75.5c-23.5 6.3-42 24.9-48.3 48.6-11.4 42.9-11.4 132.3-11.4 132.3s0 89.4 11.4 132.3c6.3 23.7 24.8 41.5 48.3 47.8C117.2 448 288 448 288 448s170.8 0 213.4-11.5c23.5-6.3 42-24.2 48.3-47.8 11.4-42.9 11.4-132.3 11.4-132.3s0-89.4-11.4-132.3zm-317.5 213.5V175.2l142.7 81.2-142.7 81.2z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Subscribe on YouTube\r\n        <\/a>\r\n    <\/div> same.<\/p>\n<p>Option D is incorrect because the interpoles do play a part in generating e.m.f.
