যে বস্তুর চুম্বক ক্ষেত্রে সৃষ্টি করে ফলে অন্য একটি চুম্বক চুম্বক পদার্থের ওপর বল প্রয়োগ করে তাকে চুম্বক বলে। চুম্বকের দুটি বিশেষ ধর্ম রয়েছে। যথা-
১. আকর্ষণীয় ধর্ম (Property of attraction)
২. দিক নির্দেশক ধর্ম (Property of direction): চুম্বক মুক্ত অবস্থা সবসময় উত্তর-দক্ষিণ দিক বরাবর থাকে। চুম্বকীয় কম্পাসের সাহায্যে সহজে দিক নির্ণয় করা যায়।
