Final answer:
The Chinese initially invented the magnetic compass for orientation in religious ceremonies, which eventually expanded to navigational use in trade and exploration. The compass was refined by Islamic innovators for religious practices, and it played a crucial role in notable voyages such as those of Zheng He.
Step-by-step explanation:
Reason for Inventing the Magnetic Compass
The Chinese invented the magnetic compass around 1000 CE, initially for the purpose of orientation during religious ceremonies and Feng Shui, rather than for navigation on the open seas. This tool, using a magnetized needle that aligns with the Earth's magnetic field, provided a reliable means to ascertain directions.
While the early compasses were not precise, as they pointed to magnetic north rather than true north, they nevertheless represented a significant advancement in technology. Over time, compass use expanded from religious and ceremonial functions to more practical applications in navigation, contributing significantly to trade and exploration.
Islamic innovators further refined these devices for calculating the qibla for prayers. The compass was an essential tool for voyages, such as those undertaken by Zheng He in the fifteenth century, demonstrating the power of China and facilitating trade.
